What do you think of the approach in
<https://git.savannah.gnu.org/cgit/guix.git/commit/?id=aecd2a13cbd8301d0fdeafcacbf69e12cc3f6138>?

The default is unchanged but the warning could be kept say until the
next release, at which point we’d change the default.

Or are you suggesting keeping the default unchanged?
