Well, I wouldn't say we have a listing facility. using Set Architecture
without an argument may list them, but that is an error message, rather than a
command to do that, which is why I don't think it is a convenient way to tell
a user to check for support. You could achieve the same if you asked for
completion, but again, not a "listing facility" in the sense of telling a user
to check.
 We could reword output from `set architecture' so as not to suggest the 
use without an argument is invalid.

 In any case the listing facility must not be an `info' subcommand, as 
these are meant for showing the state of the debuggee,

I disagree, in my opinion, this new command would function basically just like "info unwinder", giving information on how GDB is able to interact with the inferior.

 while the set of 
architectures supported is a property of the given instance of GDB itself, 
and therefore suitable for the `set'/`show' commands.  So if a new command 
it would have to be `show architecture list' or suchlike.

My understanding is that set/show commands are mostly used for when the user could change something, and the point of this command is showing the user the compilation options that were used, there's no changes that a user could do.
