Sorry for the delay ...

I will try to explain some of my thoughts.

Given you have one svn master from where dedicated slaves are syncing
Both master and first slaves are under your control so far so good.

Now some additional mirrors which are not under you full control are syncing
from the slaves to help offload traffic.

Someone hacks one of the additional mirrors, modifies a revision and adjust the
checksum (as described on many places how-to fix a corrupt repo) so it looks OK
even with svnadmin verify.

Now if you have a million of revisions it will be hard to detect such an issue.

Wouldn't it be nice to have the ability to calculate the checksums regularly so
they can be compared with the upstream checksums?

Another methode to detect such thing would be rsync the repo first with a dry-run
and then do a live sync but svnsync is preferred.
