Exactly my thought. Unfortunately tzcode itself is picky here (because I 
mistakenly made it picky when helping to write RFC 8536). I doubt 
whether anyone else is so picky unless they're imitating tzcode itself. 
That being said, we'll need to be a bit cautious here, and not introduce 
this change willy-nilly.
