I've never seen a PSTN gw properly handling a REFER, neither I think a PSTN gw should handle it (but a B2BUA/PBX) between the UA and the PSTN gw(s).
inaki,
your suggestion would mean that proxy would need to route every call between sip ua and pstn gw via a b2bua, because you cannot know in advance, if refer will be used or not.
