That was the old place, I forgot to update the documentation.

Now it is $TEXMFVAR/luatex-cache/generic/names.

I was thinking about adding to new fontspec feature, Protrusion and
Expansion, since the two are quite different and should be separately
controlled. I just need to figure out how to implement it :)

PS. You don't need microtype for luaotfload features, you just have to
set: \pdfprotrudechars2 and \pdfadjustspacing2 to activate protrusion
and expansion respectively.
