Speaking as a SeaMonkey owner (of the product not the locale).
If the turkish team did not have time to work on SeaMonkey would have
been great for me to know and I could have worked on figuring out a
solution to get us fixed here. I have repeatedly e-mailed you guys about
updating and sporadically have gotten updates but never a response.
That said, if Tae Wong or someone is willing to help you with
localization it could help not only SeaMonkey but all products you do
support and I highly encourage you approaching that.
I'm still around for talk/info regarding SeaMonkey specifically and will
continue to ship it until the experience becomes (reported to me) as
worse for your users than no localization at all. Or you tell me to
discontinue it (and how, as in what existing shipping SeaMonkey language
besides turkish would your users most likely understand, so that we can
update your users and not strand on insecure versions)
