It's only a Y10K problem if people assume that a year that happens to be 4 digits is existing in a system that doesn't permit years of 5 or more digits.

But as soon as you put a leading 0, (besides confusing people) you seem to be telling people to definitely use arbitrary fixed lengths for years and analogous purposes. Even though they weren't necessarily doing that before.

Sincerely,
