I'll assume you made a list of blocks that can be stomped, while others can be destroyed when stomping. But you missed some blocks which are unbreakable, but yet destructible by stomping. Mainly the debug blocks such as command block, chain command block, repeating command block, jigsaw, structure block and barrier. I know these are not really blocks you could find in survival, but yet, the destructibility of indestructible without exploits is slightly weird.

And just saying, this is not creative-only issue, since the unstompable blocks can't be stomped in any game mode, so you can destroy them even in Adventure mode

It just checks block hardness, will add a manual blacklist at some point
