Has something like Stonecutter been considered for maintenance of the library? It would massively help with supporting versions of the game considered LTS by the community.

Eg you could support 1.21.1, 1.21.3 and 1.21.4 at the same time.

Example project: https://github.com/IMB11/Flow

This looks promising, but it might not be the best for our recent jumps, especially 1.21.3 -> 1.21.4, but once we have our kinks ironed out (#184, #187, #190), this should definitely be something we should try and implement.
