Suggestion: Backport mod support

I believe it would be more beneficial if, when loading with the backport Mod, blocks related to that version's elements were also added.

That's an great idea, but I admit it would be a bit complicated to implement. Especially since I plan to stop adding new content to 1.21.1, to focus on the latest game update (currently 1.21.11, soon 26.1).

Of course, the new version should also be respected.
I'm not in any particular hurry. I'll wait patiently, so please take your time.
