I like it, because the implementation bug was a bit annoying to me 
sometimes.

Also, thanks for the fix for adapting sizes, back a few months. It means 
that the EC Companion/TS1 support can now become feasible. Shall I try 
to nudge that forward again?

The biggest issue is probably in typescripts and font synonyms -- should 
they directly support Berry names, seeing as that's where people will be 
getting these TS1 fonts?
