not bad, since fonts is the most complicatd part of tex (due to the fact 
that math is involved and so)

indeed, also, having all of them in mem takes space

consider typescripts to be:

\starttypescript [key a] [key b] [key c]

\stoptypescript

and all key's being optional

selecting them is a matter of best match, say [key a] or [key a][key b] or 
...  so

\usetypescript [key a] [key b]

filters all instances that match those first two keys (actually sets of keys)

the definetypeface macro (just take a look in type-ini) filters a couple of 
combinations

inside typescripts can be all kind of things but in practice it's mainly 
mapping files
