The implementation burden of 149 repeating list styles is very small too.

I have it on good authority that those are the same as lower-alpha
(apparently Swedes don't use their three "additional" letters in
alphabetic numbering contexts).

I was under the impression that the Danish and the Finnish also only used
the 26 letters of lower-alpha. Is this not true?

So far nobody has given me any hard information on the existence of an
alphabetic Welsh numbering system. Is there one? (As opposed to the
existence of an alphabet -- not every alphabet is used as a numbering
system, as noted above.)

Well, no, it isn't. :-)

My understanding (from speaking with experts on the subject) is that
actually the 90 or so keywords currently in the draft is very close to the
total number of numbering systems in active use.

There is value in such a generic system -- the problem is that there is a
huge variety of algorithms to choose from. If we introduce this, I'd like
to do so in a version _after_ the current one, since it is of much less
value than the predefined keywords, and I wouldn't want UA implementors to
consider the spec too complicated because of the presence of advanced
features of this kind.
