The "rest of the world" is mostly running software which has accepted
underscores for many years and didn't even complain about them until
relatively recently.

Ever hear of "squatter's rights"? Underscores have 'em. There's just no
practical, real-world justification to go through the hassle and expense of
eradicating them.

Whatever happened to "be liberal in what you accept" anyway? Is RFC 1123's
Robustness Principle dead and buried?
