I figured what if the timing for these types of runs changed, because I believe that timing should change. For Any% and Low Level: Time should end when the screen Wipes to black on the "Thank you" screen, right after Mario winks at us.
Why should the timing change? That would mean every single run would need to be retimed, ontop of the fact that basically our ruleset follows traditionally JRTA which ends timing on credits (for all games, not just this one) and with the fact that we have used this timing method for years now, and it is a very clear and easy way to time runs I don't see the need/reason as to changing the timing method but if you could perhaps elaborate more as to why you believe this change should be made it could help support the argument I suppose.
