I was just wondering, would there be anything speaking

against a kind of wrapper that is able to load older mods?

I am thinking about something that loads mods in a kind of

environment, providing old API functions, which are then

either piped directly through to the real system or are beeing

emulated by using the current api functions.

Older Forge versions would be a good base for implementing that

environment. There could be a configuration file that tells

which specific version of MC you want to emulate.

Just in general, is there anything that would really speak

against such a wrapper/system?

Sorry if there was already a similar question.

No. Minecraft has something called obfuscation, which prevents such a cross-version thing from happening.
