It can't even do that, e.g. single remotes (even the dumb ones) can send
different code groups (addresses) for different keys.

I think setting the keytables for each logical device would do.

I.e. just have a way to create additional logical devices. Each can have
its own keytable. The decoders would send their output to all logical
remotes, trying to match the tables etc.

That would mean unnecessary limiting.

Precisely.
