I intend to use it! So, yes, I had not used it at this point, and your explanation now makes sense.

In the test example I have, I have now placed a line:  \ss My text, and I see that it now loads the sans serif font. But can you explain why it loads the math font, given that I have not, as yet, used that anywhere (and may not - it is there for insurance in case such a glyph is needed)?

Can someone tell me why, when I define my typefaces as follows below, I get:

mkiv lua stats  > loaded fonts: 2 files: baskervaldadfstd.otf, 
texgyrepagella-math.otf

when in fact my font definitions are:

\definefontfamily [mainface] [rm] [baskervaldadfstd] 
[tf=file:BaskervaldADFStd.otf]
\definefontfamily [mainface] [ss] [librisadfstd] 
[tf=file:LibrisADFStd-Regular.otf]
\definefontfamily [mainface] [mm] [TeX Gyre Pagella Math]

\setupbodyfont[mainface]

---------------------

ConTeXt loads the [rm] and the [mm] but not the [ss]. Be assured that 
the ss typeface is available. So if, for example, I comment out the 
first line ([rm]) and change the Libris to rm instead, I am told:

mkiv lua stats  > loaded fonts: 2 files: librisadfstd-regular.otf, 
texgyrepagella-math.otf

In other words, only two, not three definitions are working at any one 
time. Or is it not accepting [ss] for some reason regardless? I have 
tried any number of existing sans serif fonts and none of them will 
load. I know the family names are correct, so that is not the problem. 
What could I be doing wrong?
Are you actually using sans serif text in your document? If not, then context has no reason to embed a subset of it in the PDF. It is the same reason by the teletype [tt] font has not been loaded.
