This would be helpful for when Mojang releases patches for Minecraft of the current version like 1.16.0 to 1.16.4 so if you created the pack on previous patch you should be able to change that small version difference.
What I had in mind would be a feature to change the game's version of a profile. The launcher would still show all the mods it had in the old version and then you could try downloading those mods by clicking that "download latest version" button. If no new version is there, it would fail or something (show the mod as missing). That would make updating a whole lot easier. Especially when talking about those minor updates (like from 1.16.3 to 1.16.4)
