As I understood things in ALPS, each application protocol has its own
settings so I don't see there being too much problem with the disjoint
number spaces. It is a bit fussy but it avoids having to rework existing
stacks to parse frames that don't belong to any streams.  From the stacks
that I'm experienced with, frame parsing and stream state are wrapped
tightly. Unless you mean that you expect an endpoint to use parsing
primitives to parse a frame, which seems like it would duplicate things.
Instead just having unframed settings that carry properties of a
yet-to-be-fully-instantiated endpoint connection seems something to have
less impact. But of course YMMV.

Cheers
Lucas
