That is interesting, but maybe it hasn't been like this before.
My *wild* guess is that:
- when you send out the announcement to the ctan mailing list, the two
  are in sync
- but Karl has some (hidden?) way of seeing files being update on the
  CTAN server, and pulls from them, probably *before* the announcement
  was made

(Also, because not ALL updates have announcements, so relying solely on
announcements is a no-go).

In any case, I think it would be good if we = CTAN and TL team would
talk about this how we can optimize it.

We/Karl does not rely on any announcement emails as far as I know.

Let us discuss this with Karl and the CTAN team off list.

I don't understand what you want to say here. Updates are updates for
tlmgr, without any distinction. tlmgr does NOT look into the actual
files, only the changed revision. So there is no way that tlmgr can tell
you that this updates is only a meta-data update.

Best regards
