> FWIW the OED says both are fine: writable, a. Also writeable.

English has no equivalent of l'Academie Francaise, and that includes the OED.

It's about general usage, in practice. Whether "both are fine" is really beside
the point. There are lots of English expressions that are fine or that are used
in some contexts by some people, but which if used generally will get you stares
of incomprehensibility most of the time.

"writeable" is relatively little used, which means that users who go looking for
matches for "writeable" will generally be handicapped wrt what they find.

Please see the bugs I referenced for other software, or google for yourself, to
see how others are handling this. Again, maybe everyone in the world is wrong,
but it's about helping users find what they need.

Google, BTW, is smart enough to return "writable" hits for a "writeable" query,
but grep, Emacs search, etc. are less forgiving.

Again though, not the most important bug.
