Yes, if glibc adds this functionality to getopt, gnulib will want to
import that code from glibc. Because it does not make sense that a program
accepts localized option names on some systems and not on others —
that would be a documentation problem for that package as well as a
usability problem for its users.

Correct, and thanks for pointing to it. Yes, this was stated in the
announcement [1]:
  "Code shared with other GNU packages via Gnulib will continue
   to require assignment to the FSF."

So, if glibc wants to accept Vivien's patch, Vivien will need to
exchange copyright papers with the FSF [2].
