It is one thing to have a mechanisms that makes it incrementally more
difficult for an attacker to succeed. It is quite another to make it no
at all. If all the attacker has to do is register a new name and use a
string-replacement on their previous attack, we do not have any meaningful
Dave, this actually reads as though you suggest we throw out ADSP all
together. I don't see how this limit doesn't apply to ADSP regardless
of tree walking functionality.

Asked, yes. Answered, I don't think so.
Well, I certainly proposed one potential scenario where sub domain
locking would be useful (to me, arguably not to you). Archives suggest
Michael Hammer would prefer sub domain locking, as have Jim Fenton's
comments. Perhaps they could theorize an example or two of where and
how this would be useful to them.
