since there seems to be no subcategories for just speedrunning the world 3 micro-trials in the classic pack leaderboards, there should be some thinking about whether to have classic pack trial speedruns count towards flash w3's trial runs, or should be counted seperately

They will be counted separately, because World 3 will supposedly have some more substantial changes in the final version. Considering nobody has done any speedruns for the main categories in early access yet, there definitely doesn’t seem to be any reason to add a time trial category right now.
