I'm relatively new to speedrunning and not really active on these boards, but I guess I don't see why there's any problem with categorizing separately considering the number of runs that have been completed without it. A lot of games discover new glitches/issues and end up adding categorizations/filters/etc to the leaderboards to accomodate this. For example, Super Metroid has the overall leaderboard, but allows for filtering based on boss order so you can see how people do with different routes. Why this can't just be added as a filter on the main board, with having it unfiltered be the default, I don't know.
I personally think this glitch would make my stream less watchable, so I'm personally not going to use it, and I think there are quite a few others who have similar concerns. If the community wants it the other way, and the results currently are leaning that way, I guess I'll just have to watch myself tumble down the leaderboards, and that's fine. It certainly will make me a LOT less likely to continue running this, however, if everything is lumped in together.
