I guess I just don't understand what the vulnerability is when HTML
is allowed to pull back into a form the path info for a file field upon
resubmission.

Can you give me a concrete example of an exploit that can be built
into a website that might be used if the change I suggested occurred.

And, no, I wouldn't want everyone to have to stop wearing a helmet
just because I might choose to not wear one.  But that's a bogus
argument anyway.  If lawmakers were really trying to save money
from uninsured motorists injuries, they would force car drivers to
wear helmets, also, which would protect far, far greater numbers
of injured, uninsured motorists.  But they don't do that...why?
Because it would be a great inconvenience to the vast majority of
lawmakers who never ride a motorcycle.  So, if it doesn't affect them,
they don't care.

No, that's not what I meant at all. I meant exactly what I wrote: any
malicious programmer could exploit it in their own web pages. Just like
malicious programmers exploited ActiveX vulnerabilities in IE, and
cross-site scripting vulnerabilities, etc, etc. If the browser lets you do
something, it lets ANYONE do that thing, not just Rick the trustworthy
programmer.
