Not so much changed, but that there was previously no standard. 
The W3C was displeased with the proliferation of ad-hoc, 
inconsistent font MIME types and created [SOURCE].

For people who deal with MIMEs, yes, but how does this affect a 
package manager like Guix?  We don't.

Are you talking about 5483a2d0a913fe533744699e9ef5757c6e3f6983?

Aside... I know others have mentioned this before, and this is 
another example of a commit that should have been split.  It 
silently moves the TTF fonts from /share/fonts/truetype to 
/share/fonts/ttf for reasons that aren't explained anywhere and 
aren't related to the stated goal.

Was this RFC the reason?  If so you're confusing two unrelated 
things.

  $ ls ~/.guix-profile/share/fonts
  cantarell/  opentype/  truetype/

(Seeing this I might change cantarell to use ‘opentype’, or not, 
because it's purely a matter of taste.)

These directory names are for humans.  I think ‘truetype’ was 
better than ‘ttf’.

Kind regards,
