Just wondering, might we be able to use an external tool
for subsetting OTF fonts before they are included by pdf[la]tex?

There is this tool, I have no diea how solid it is, never tried:

https://fonttools.readthedocs.io/en/latest/subset/index.html

| pyftsubset is an OpenType font subsetter and
| optimizer, based on fontTools. It accepts any TT- or
| CFF-flavored OpenType (.otf or .ttf) or WOFF (.woff) font file.
| The subsetted glyph set is based on the specified glyphs or
| characters, and specified OpenType layout features.

Might that be a way?
