May be [e-mail] would have been a better place?

That's the whole point, I believe. Subaddressing has always been a
matter of local conventions (like the [e-mail]
convention in many environments), not needing to be "described".

If I understand you well, you suggest to create (not describe) a new
concept, "global subaddressing", with a standard delimiter and
subaddressing-aware software, allowing new tricks (like the MLM you
mention, which accepts mail only from subscribers and who can
recognize them even when they use subaddressing).

That's may be a good idea but it is something new, not a description
of a current practice.

Can you explain why the MUA and the MSA need to know it?
