Hm, indeed.   Unfortunately, it is not quite easy to find "the" new RFC,
there was quite a number of correcting and extending RFCs issued over the
last (almost) 30 years, which is not that surprising...

Are we going to do something about it?  Is it likely that relaxing/changing
the rules on our side will break any possible workarounds that people might
have employed to make the search work like they want it to work?
