It doesn't need to be _generated_, it just needs to exist.
|xparse-generic.tex| and the |xparse-<date>.sty| you mention are no
longer generated from |xparse.ins| because the development version moved
to |ltcmd.dtx| in latex-base.

Also, the |texlive-2020.1| tag is frozen and doesn't get any more
updates.  I'd recommend you use the |trunk| version (updated daily),
which has the newest LaTeX, that I mentioned.

No, nowadays that file is frozen and won't change, so you'll have to
just copy it verbatim.

Exactly (I am the one to blame :-).  |xparse-generic.tex| was generated
then modified by hand, but I forgot to add a similar note on its header.
