Answering myself...
The only "unspecified" I see is this:
If the shell is not currently executing a function or dot
script, the results are unspecified.
which clearly does not apply to the version before this patch (we
are executing a dot script). And
The return utility shall cause the shell to stop executing the
current function or dot script.
would mean that we are correct to expect that "should not get here"
is not reached, as the "return 5" would cause the shell to stop
executing the dot script there.
So "while this is allowed by POSIX" may be a bit misleading and
needs to be reworded, I guess?
