Whether or not you implement hacks for poorly designed router
firmwares as you have done for other sites is entirely up to you.

And in general, users don't ever try to update their router firmware
in the first place. Those that do are likely smart enough to use
Google to figure out how to work around the problem.

And Firefox, Safari, and Chrome independently didn't find enough
compatibility issues to worry about.

In addition to changing Firefox, Safari, and Chrome, implementing
fakepath would require teaching every web developer to use
foo.value.substr(12) or foo.files[0] instead of foo.value. Confusing
and unintuitive behavior like this makes HTML more difficult to learn,
and this added cost of learning should not be ignored either.
