Deprecation of the polymorphic signing algorithms WILL NOT break existing
usages that already work, including those in RFC 9528. They can continue
without any impact.
What deprecation DOES do is indicate that new applications and specifications
should choose the fully-specified algorithms instead.
I'll note that RFC 9528 states that "Algorithms need to be specified with
enough parameters to make them completely determined." This is exactly the
purpose of the Fully-Specified Algorithms specification.
I hope this clears up any confusion.

(Adding cose and lake)
Apologies for a late response, I just realized this also has an impact on
registered COSE algs.
The deprecation of COSE algorithm registrations in section 3.2.2 of
draft-ietf-jose-fully-specified-algorithms-02 breaks the construction of cipher
suites in RFC 9528/9529. This is implemented in products on the market so the
train has already left for this type of rearrangements of the IANA registry.
I have nothing against registering more specified algorithms, but the existing
registrations in 3.2.2 must not be deprecated.

Subject: [jose] WGLC for draft-ietf-jose-fully-specified-algorithms
JOSE working group members,
This email initiates a three week working group last call on the following
document:
https://datatracker.ietf.org/doc/draft-ietf-jose-fully-specified-algorithms/
All open issues have been resolved. Additionally there does not appear to be
general support for including fully-specified ECDH algorithms.
https://mailarchive.ietf.org/arch/msg/jose/ZHDlXENvTwjlWxTVQQ2hkNBX4dw/
Please review the document and post any final comments along with your
recommendation on whether or not it is ready to proceed by the Monday 27 May.
Thank you,
JOSE chairs
