Seems fine. If you feel like it, I could see us remove the traces in the documentation about bro-pkg.meta still.

It might also be good to document somewhere the fact that we keep this alive because it resulted in a number of packages being de-listed (https://github.com/zeek/packages/actions/runs/7920368845/job/21623249606)
