I was thinking about that in general.  Netscape had some of its own
unusual constructs that would escape normal XSS filters.

But you see this kind of stuff all over the place in A-V, even with
corrupted files that are rejected by most - but not all - tools (e.g.
CVE-2005-3210 through CVE-2005-3235).

I think this kind of happened with MS-DOS device names a number of years
ago, when it used to cause a blue screen.  Various products had to put in
defenses/workarounds to protect themselves against what was basically an
OS bug.

One can hope ;-) although it's a rather interesting example of how
apparently cosmetic design choices can have major side effects.
