Alright, I have filed the bug on the fontspec bug tracker:

https://github.com/wspr/fontspec/issues/437

If that doesn't go anywhere, I will try at latex2e's (their bug tracker
is much more active than fontspec's).

As another workaround, I have managed to change the font family name in
the OTF files of Jost* using the following fontforge python script:

   import fontforge
   import sys

   for fontname in sys.argv[1:]:
       font = fontforge.open(fontname)
       font.familyname = "Jost"
       font.generate(fontname+"-starless.otf")

After installing the generated "starless" fonts, I can use them with
xelatex as "Jost" (without asterisk).
