I agree.  I have found native screen support for braille displays a few
years ago basically by accident during a code browse.  While it might
historically be interesting that the GNU screen package directly
support(s|ed) braille displays, I don't think many (if any) people
actually use that.  At least on Linux, BRLTTY is superior regarding its
functionality and driver support, and everyone knows that.  I am not
sure about other operating system kernels, but even if we considered
*BSDs whigh might be interested in such a feature natively provided by
GNU screen, there is virtually no support for current hardware models
in GNU screen.  So dropping that part of the code seems like a sensible
thing to do.  The alternative would be to improve it *a lot*.
