Current apt frowns upon such a file, but presumably that could be fixed
in forky.  I suppose forky could still rely on PGP by default, but could
support Sigstore/Sigsum/SSH/minisign/signify/whatever in addition to
PGP, if people turn a knob.

I don't know how things are implemented on the server side, or who the
responsible people are -- I suppose some people may consider it less
risky to introduce a new file and migrate to it, than to modify the
existing InRelease files.

Yes -- that should be fixed.  From a specification/policy point of view,
I think what should be done is simple: forget about Release+Release.gpg
as obsolete, and only use InRelease files.  What to sign is the YAML
content with all lines ending with EOL.

Right now there is ambiguity: the InRelease signatures are computed on
Release content without a terminating EOL, IIRC.

Or are you aware that cleartext canonicalization is used for anything
but the terminating EOL?  I think the only difference between
unprocessed Release content and processed InRelease content is the
terminating EOL, which I don't know the history for but presumably is
for some historic reason.

Some new policy could demand that YAML archive info ought to be
formatted in a way that survives identically PGP cleartext formatting.
I think that subset covers reasonable files.
