No, not after someone pointed out that it could have strange side-effects
on full text search configurations that used unaccent.  You'd stop being
able to find documents whenever your search term is stripped of accents
more thoroughly than before.  That might be all right in a new major
release (if it documents that you might have to rebuild your FTS indexes
and derived tsvector columns).  It's not all right in a minor release.
