I understand, but I was curious why these 12 files do use the
variable, while all the rest don't.  IOW, what is (or was) so special
about these files?

I think I'd like to wait with the decision until we hear the
emacsspeak results.  I expect that the effect on the memory will be
minor, even in a package _all_ of whose files use this variable.  If
that is indeed so, I think we can disable the variable.
