Michael,

This is very interesting indeed, and I had seen it before, probably from reading the documentation of one of your font packages, but I had forgotten about it !

For people interested:

texmf-dist$ find . -name '*.fontspec'
./tex/latex/baskervaldx/baskervaldx.fontspec
./tex/latex/erewhon/erewhon.fontspec
./tex/latex/fbb/fbb.fontspec
./tex/latex/heuristica/heuristica.fontspec
./tex/latex/inconsolata/Inconsolatazi4.fonatspec
./tex/latex/newpx/TeXGyrePagellaX.fontspec
./tex/latex/nimbus15/nimbusmono.fontspec
./tex/latex/nimbus15/nimbussans.fontspec
./tex/latex/nimbus15/nimbusserif.fontspec
./tex/latex/nimbus15/zco.fontspec
./tex/latex/nimbus15/zcoN.fontspec
./tex/latex/nimbus15/zhv.fontspec
./tex/latex/nimbus15/ztm.fontspec
./tex/latex/tempora/tempora.fontspec
./tex/latex/xcharter/XCharter.fontspec

I am not mistaken all those (of whom a vast majority, if not all of them, is among Michael's contributions to CTAN) come with LateX font packages and NFSS font definition files for 8bit encodings.

The "*.fontspec" files seem much easier to set up than the "*.fd/*.sty" files, and perhaps an effort (don't look at me ;-) ) should me made to accompany _all_ OpenType TeXLive distributed fonts with matching ".fontspec" configuration files ? 

This could originate with TeXLive itself or come with "fontspec" or possibly be a separated package ?

A master in perl (surely bash scripting is enough) could write a script examining the filenames in texmf-dist/fonts/opentype and make the creation of all those .fontspec files semi-automatic ...
