I think Ludo means that we should provide the most useful options (like
the fontconfig dirs) as dedicated record fields, while leaving an
"extra-config" escape hatch, that can be used with SXML or a raw string
for stuff that's too complicated (my personal preference would still be
SXML over the raw string, but YMMV).

I'd prefer extra-config over include – extra-config doesn't need to go
through file-like objects and an additional layer of G-Expression
quoting.
