Helpful to humans yes. primarily? i'm not sure. probably.

Easy enough to answer with a bit of surveying probably.

Have you considered giving feedback on the W3C Note?
Parsing a "single normal space character ASCII 32" (rather than just "white
space") should be equivalently easy to parsing a "T", and thus since they
are equivalent from a computer point of view, you could make the argument
that the W3C Note should be extended to permit either since the space is
more human friendly.
Then we could simply profile that and recommend that folks SHOULD use a
I'd just like to see this argument pushed up stream, because I think it has
a decent chance, and would benefit many others.
