There is nothing wrong with needing some insight, it's like knowing which characters a combo works with and those who doesn't, but with stages instead of characters.
That's not even REMOTELY comparable...
Which characters combo and which don't is intuitive based upon the size and weight of the character. Even things like which stages you can go UNDER or tech off the side of are based upon the size and shape of the stage itself.
In the case of Bowsercide, one "bottom of the screen" is identical to every other. There is no appreciable difference based upon game logic.
This is simply a bug.
Cherrypicking: few companies actually fix stuff like that.
Can you name another developer that has left a bug in a game where, by doing the same thing on different levels, the outcome of a match will be different?
Seriously, if Valve introduced a bug where a soldier killing the last enemy and himself simultaneously on SOME arena maps awarded his team the win and others awarded the other team the win, it would be patched less than 24 hours later.
That's why we don't just go black or white. We'd need to know what "clearly won" would mean in this scenario.
It was crystal clear for years before Nintendo introduced this bug: the initiator of the suicide move is declared the winner.
And that's the other thing: the game SHIPPED with the exact same rules as Brawl. Have we even had official confirmation that Sakurai wanted to change it to be anything like this?
and the game already knows who has priority.
The game doesn't "know" who has priority. The game is haphazardly tossing priority out arbitrarily because it's
bugged.
Do you honestly believe Sakurai wanted us to remember which of the following stages do what?
Normal Stage Sudden Death
Final Destination
Delfino Plaza
Castle Siege
Custom Stages (wont be used, but thought it would be nice to know)
Duck Hunt
Normal Stage Bowser Dies First
Battlefield

Bowsercide already has plenty of drawbacks and difficulty surrounding its use:
1. In order to use it, Bowser must be sufficiently ahead in % of his opponent.
Given how easy it is to combo Bowser and rack damage on him, throughout the normal course of a match, Bowser should almost
never be sufficiently ahead of his opponent to steer the move over the ledge. If he is, it's because the Bowser player is simply playing THAT much better and deserves the win.
2. The move is difficult to land
Klaw has been severely nerfed since Brawl (where it always awarded Bowser the win). Not only has its hitbox been substantially reduced, but the lack of grab armor means pretty much anything can interrupt it.
3. Tradition has always dictated that the initiator of the suicide move wins
When a suicide move kills both players simultaneously on the last stock, the win has always been awarded to the initiator of the move. This avoids characters with suicide moves having those moves used against them (and Bowser is already crap enough).
4. There is clear evidence that this is not working as intended
Until someone can demonstrate that there is sufficient reason for Bowser to die first on some stages and die simultaneously with his victim on other stages, leading to sudden death, then we can use our
brains and come to the conclusion that this is a
bug.
In fact, this is the bug they were trying to fix when they borked Bowsercide:

Developers accidentally introduce bugs when patching all the time. Developers who give a rat's hairy butt usually go in and fix those bugs in short order. Let's not confuse Nintendo's lack of care with their genuine intent that stage choice should affect the outcome of Bowsercide.
Until they actually fix the bug and make one thing happen or the other (always SD or always Bowser loses), stick to the old suicide clause: initiator wins.
