Code review comment for ~mirespace/ubuntu/+source/libmail-dkim-perl:reverting-upstream-debian-ed25519-noble-proposed

Thanks Andreas!

It makes perfect sense for a user to trust that a new package version will come with all the features announced upstream.... thanks for bringing up this point.

I checked spamassassin versions and we are in 4.0.0 since Mantic, so new features that can come in -proposed libmail-dkim-perl version are not in use yet:

 spamassassin | 3.4.6-1ubuntu0.22.04.1 | jammy-updates | source, all
 spamassassin | 4.0.0-7ubuntu1 | mantic | source, all
 spamassassin | 4.0.0-8ubuntu1 | noble | source, all

for libmail-dmar-perl is the same case:

 libmail-dmarc-perl | 1.20230215-1 | mantic/universe | source, all
 libmail-dmarc-perl | 1.20230215-1 | noble/universe | source, all

Only for the records, the changes that come with the dkim -proposed version are:

1.20240124 2024-01-24 UTC
  * ARC: Return fail for any ARC set with an instance number greater than 50.
    This brings ARC verification in line with DKIM verification limits.

1.20230911 2023-09-11 UTC
  * Option to add custom tags to generated ARC signatures and seals

1.20230630 2023-06-30 UTC
  * Add support for Ed25519 signature types
    Thanks to Matthäus Wander @mwander
  * Option to add custom tags to generated signatures

So I'm okay with adding libmail-dkim-perl to the sync-blocklist.
