This part seems an unintentional change?

No, I upgraded the security advisory to show a current one with the git part.
I took a random security advisory

I'm on the fence of this, we haven't reached to the point to decommission svn (mirror) entirely. The point will be the EoL of stable/12. There is still requirement of using svn to get the latest code, however, I would recommend the new setup directly use git to get the latest updates. If we're not removing svn bit for now, let's add some more notes about git is the preferred way.

ok, I'm not sure if modifiying the EN/SA needs signing by so@, but that's a good point to update those instructions.

Without me seeking its point of origin: this phrase may be a source of confusion.

As far as I know – correct me, please, if I'm wrong:

• stable/12 is not legacy.

It may help to note that 12.3-RELEASE is production quality but not legacy in the context of recently approved https://reviews.freebsd.org/D37235.

Digging deeper, via the comment above commented-out text in a September 2022 commit:

… I see no legacy release.

No mention of legacy in the February 2015 'Changes to the FreeBSD Support Model' https://lists.freebsd.org/pipermail/freebsd-announce/2015-February/001624.html.

Updating the example SA is a good idea independent of the removal of SVN instructions. Please go ahead and commit this part.
