originally "euler" is a math companion font to "concrete" and it's not 
trivial to make en euler with all text styles (maybe some day the tex 
gyre project will give it a try) .. btw, the same is true for sans 
fonts: at some point one runs out of distinctive features

btw, it also fits with pagella (see type-imp-euler)

most users who mess with fonts either use the selectfont mechanism or 
peek into the type-imp files to see how to set up a combination

In what sense?

Anyway, there is quite some documentation (also about fonts) available 
(and the context distribution documentation section has examples).
