Committee members sometimes just open issues for really simple new
feature requests, but that tends to work well only for those who
attend meetings and/or are frequent contributors.

A paper is probably best, even if it is very short. Papers just plain
carry more weight, and are read by a wider audience.

Out of curiosity, size_type of what?

Also, iterator_traits is viewed as an anachronism by some influential
committee members, both because of the lumping of multiple traits into
a single class and because of the problems using the current
iterator_traits with SFINAE. So you might want to consider a set of
replacement traits that follows modern practice. Proposing something
like that for Boost would be a good start.

Incidentally, I've got a boostification of an is_iterator trait
contributed by Howard Hinnant which would be a nice addition to a
generic set of iterator traits.
