It is quite sensible; the draft can be implemented in ca. two weeks of
coding. It can be done with good performance with rather small tables:
2 KB for the prohibit table, 7 KB for the lowercasing table, and a
similar amount for the composition tables needed for UTR15.
But the draft leaves two questions open:
- Is Han folding (canon-2.3) completely removed from the proposal,
or is it only postponed until a later draft? I'm noting that a
different draft says "There are no well-established rules for
such folding, and some of the proposed folding would be
locale-specific." - therefore Han folding appears not to be suitable
for inclusion in such a canonicalization engine.
- What is the encoding in which internationalized domain names are
exchanged between DNS servers? UTF-8 or UTF-5?
