No, folks could misinterpret U+NN as "anything up to 6 digits".

+1  Obviously John hates it, that would justify "often".  Others don't
like backslash-U for various reasons, not only ugly and awkward, also
confusing (due to various conventions), unclear (lack of delimiter),
and a royal PITA in conjunction with <quoted-string>, when it results
in multiple backslashes.  "Harmful" is worse than "ugly and awkward".

IMO not "all", folks are supposed to know RFC 3629, it's a STD.  So far
all attacks on the "three steps" model fortunately failed, STD is STD.
