Thanks to you both.  I've now completed revising my test scripts,
including using \parskip in ABOUT.tex.  In the unlikely event that
anybody is interested in what they cover, the scripts are now at
https://www.linuxfromscratch.org/~ken/TL2023/  (the 20230807
tarball) with an updated ABOUT.pdf listing what they do, and also
now listing which collections are required for people using the
binaries.

I hope to get back to looking at OTF and TTF fonts to see what they
cover, for that I intend to change the file to using \parskip, I
suspect a few of the languages I consider might need me to increase
baselineskip, time will tell.
