My personal short answer to this is no.
My reasoning and long answer is this. In my opinion, the point of a speedrun is to beat the game as fast as possible. You're attempting to push the game to its limits and get the it takes to beat the game down. Instant kills are an intended mechanic and help do this. They are fast on most characters and 100% should be and are allowed in every category. Until the game is more optimized and needs to be revamped, I don't believe disallowing usage of any strategy is the correct approach.
The second reason that I will give for this is the limited number of active player on this game at the moment. There are only three of us. Splitting up competition even more than it already is would not be good in my opinion. We already have quite a few categories, with each character being split into its own separate category, that I feel more categories at our current point would split competition further and not be good for the game.
My third and final reason I will give at the moment is this. We just recently cleaned up the boards. Everything is nice at the moment and there are still categories that have no runs submitted. This kind of ads on to my last point, but i feel adding more clutter to the boards after just removing clutter is very counter productive. Lets fill in the empty runs, share the game around, and focus on optimizing strategies. Once everything is a little more optimized, we can revisit the idea of no instant kill boards because i believe, at their core, they aren't the worst idea. I feel like no instants could be super interesting eventually, I just feel like now isn't the time.
No one is stopping you from not using instant kills. While I personally speedrun this game to push it to its limits, it is completely viable to just speedrun it for fun. At the end of the day you SHOULD be speedrunning this game for fun and if not using instant kills is fun for you, go for it! Your runs will be accepted with or without them. Sorry if this isn't the answer you wanted and hopefully i make sense with my reasoning. I look forward to seeing more runs submitted by you in the future.
