I mean, you could say the same thing about HSTS and key pinning.  Domain changes hands, but &quot;oops&quot;, HSTS was set and the old keys were pinned.<p>Is that actually a problem? No, it&#x27;s not.  Similarly, as the owner of a new domain, why would I want the <i>old</i> content?  The only reason I can think of is that I brought a company outright, or something.  In that situation, if I don&#x27;t want to change the content, everything still works.  If I want to change it, and they did something stupid -- like unversioned paths using this proposed flag -- then yeah, I&#x27;m in a weird spot.  That seems like the most trivial and unlikely of scenarios, though.  It requires such a complex chain of events to occur.<p>I think it&#x27;s safe to say that malicious usage of the flag is entirely out of scope when considering the validity of it, again, because it requires a contrived situation.
