ed448 sub-keys allowed for Debian Developer?

Hi,

Does the Debian infrastructure, such as:

 * HKP server keyring.debian.org

 * (forgot the name) the software that checks signature of changes/dsc
   files on uploads

support ed448 sub-keys? If not, maybe ed25519 sub-keys? My previous
signature sub-key has expired, and *cough* *cough* my first upload in
*cough* *cough* 10+ years is being rejected because of that. The ed448
signature sub-key I uploaded to keyring.debian.org strictly before 27
June seems not have been part of the 27 June update, I guess the
reason is ed448 sub-keys not being supported? So I'm checking what kind
of signature sub-key I should create for that now.

Thanks!

Lionel
