I'm fine with this, perhaps immediately after 2.17.0 comes out?
Provided that the regtests compile, I have no trouble switching to
it for 2.17.1 regardless of what that might do to user scores
(since nobody should be using 2.17.1).

Note that GUB will need to be updated to compile guile V2, and
also that if that update is done poorly then GUB would lose the
ability to compile 2.16.x.  IIRC that happened with the 2.12
branch, or at least the compile needed some manual hacks in order
to complete the build.
