\sc is more somthing mkii ... when type1 fonts (in an 8 bit universum)
smallcaps and oldstyle and such meant using a different font

nowadays one can turn them on/off as features and when you need them a
lot you can even define an extra bodyfont variant from them and switch
to that one when needed

now, when smallcaps and oldstyle etc became features instead of font
properties that didn't mean it always became easier because when
opentype came around there was no 'recipe' or possibility to define what
is default; for instance some fonts default to oldstyle in the sense
that these shapes are in the default slots and you need to turn them off
instead; also one needs to keep in mind that some features are language
/ script dependent and fonts differ in what they do default

summary: see smallcaps as features but always look at what the font
assumes and does by default; be prepared for inconsistencies (after all
this is why we want/need control over what context does with a font)

That is good to know, thank you. While replacing all \sc with \smallcaps in a document I work on, I realized that in a \setuphead I had 

style={\sca},

What is the correct substitute for that?
