It works for me on texlive 2023 with your new module file.

Yes, the copy I got has in the footer 

Sold by the PDF Association to Ulrike Fischer  | April 5, 2023 |
Single user only, copying and networking prohibited.

I wouldn't distribute it for the same reason I wouldn't distribute
pdf copies of the TeXbook.

> What happens when the sponsors withdraw? 

What should happen? I bought a copy at a very good price (0€) and
now own it. If the sponsorship ends and the price goes up to 200 CHF
again nothing changes for me. 

> What is there are updates (unlikely anyway).

Amendments to ISO document typically have to be buyed too, e.g.
amendment 1 (which is part of the bundled offered by pdfa) normally
costs 17 CHF. 

Personally I think that the PDF Association made a very good job
here (they worked hard on it), I'm quite grateful for it and I hope
that there will more of these offers (personally I would like to get
pdf/A-4 and the upcomming pdf/UA-2).

Re: [NTG-context] tikz error upgrading to texlive version (artix)

It fails for me in texlive 2023. 

I don't know who changed what here, but it looks like a catcode
problem. context loads tikz files in m-tikz.mkxl with
\tikzinputfiles, and that calls \setcatcodetable\texcatcodes. After
that ~ has catcode 12 and that breaks the \let~\pdfmath@char@quote
in the pgfmathparser.code.tex file 

\begingroup
  \lccode`\~=`\"
  \lowercase{\endgroup
\def\pgfmath@catcodes{%
  \catcode`\==12 %
  \catcode`\,=12 %
  \catcode`\|=12 %
  \catcode`\&=12 %
  \let~\pgfmath@char@quote
}}%

This basically doesn't work (quite unrelated to the tex code). 
The PDF viewers have all their own mind here and none of them is
really "code friendly". See e.g. 

https://tex.stackexchange.com/a/472112/2388

It works sometimes a bit better if the PDF is tagged, but there too
you can't currently rely on four spaces staying four spaces (and not
all PDF reader understand tagging).

Better attach files with code.

Interesting how near people can be ;-) I will have to go over the
bridge ...

You could look at previous TUG videos to get a feeling
https://www.youtube.com/@TeXUsersGroup/playlists but imho you
shouldn't worry.

Re: [NTG-context] LMTX generates PDFs with non-working fonts on real printers

I saw that the new code renumbers the glyphs, so it uses 0001, 0002
etc instead of the mix of various slot numbers in luatex. Perhaps
the printers don't like that.
