Your assumption is incorrect: the performance of public SVN servers
would suffer greatly! Why do you think we have the svnrobots.txt file in
the CommitMonitor?
http://tools.tortoisesvn.net/svnrobots

Yes, that was implemented before we went public. But I had several
admins already asking for that feature (they haven't seen that page
before) because their servers were under way too much stress, and some
even went down completely.

Every two seconds? Do you know how long it takes for a server to answer
one such request?
What you're suggesting would bring most servers down.

I've rarely seen an svn server which was hosted alone, i.e., withoug the
server being used for other stuff too.
