It make sense if it indeed works in practice.  You seem to say there
are in fact ABI incompatibilities in the 2.0.x series, and if that's
indeed true, then the only way to avoid trouble is to rebuild and
reinstall all the packages that are linked against Guile, once I
install the latest Guile.  That is unfortunate, to say the least,
since Guile is already used in important GNU packages such as GDB and
Make.

Is it possible to publish the list of ABI incompatibilities between
2.0.11 and 2.0.12 specifically?

Thanks.
