Am I missing something here?  Because diffoscope 274 is already in trixie.  And
the issue isn't a result of a change to diffoscope itself but a result of
python3-cryptography (imported by python3-pypdf, which diffoscope recommends)
not working without openssl-provider-legacy (or a workaround).  So presumably we
will see the same issues in trixie when openssl migrates.

Interestingly, python3-cryptography isn't actually a dependency of python3-pypdf
(it recommends python3-pycryptodome instead).  But it tries to load cryptography
-- which something else must have pulled in -- first, and only catches
ImportError, not this RuntimeError.
