Hello,
"temporary" can take surprisingly long if one of the linking packages
suddenly develops a build error. ;-)
And one can get a surising amount of bug reports from people doing
partial ugrades, too.

I somehow missed that fact in my considerations. (I think that at some
point the RM considered changing the testing migration infrastructure
to allow keeping old, "orphaned" binaries around to simplify
transitions. - I am not sure whether this was ever implemented.)

I do not think we have ever done that, making a stable-update just to
introduce versioned symbols. - Needs doublechecking with -release.

I think GnuTLS being listed as part of the guile-1.8 removal is an
error in the reporting script, GnuTLS has moved to guile-2.0 in 2013.
OTOH I hope we can have gnutls linked against nettle 3.x without
needing to update to 3.4.x. (Which would couple together two
transitions. And 3.4 ist still a development release.)
