Oh, great...

So we probably should take this into consideration *now*, even though 
most guile consumers aren't ready for the changes in 2.2 yet.

Fortunately, it seems guile itself has taken their own instability into 
account:

https://www.gnu.org/software/guile/manual/html_node/Parallel-Installations.html

Although looking at packages which use guile, most haven't fully adapted 
to this yet (guile-config is still used by some, and it doesn't seem 
anyone is using pkg-config to find guile and guild), so we still need to 
provide unversioned binaries/scripts in /usr/bin for now.

It's way too early to make 2.2 "the" guile, so I think we stick with a 
versioned guile1.8 for the stragglers, and 'guile' being 2.0 for now, 
but eventually transitioning to a versioned 'guile2.0'.  We'll have to 
take another look at this once the real world has adapted to 2.2.
