On a practical note, we don’t tend to prefix zeroes to numbers because they are superfluous. If programmers are using strings to store a year and those strings are limited to four digits, your project likely has a host of other issues that will become problems long before Y10K.
We already have a precedent, in programming, for prefixed zeroes having meaning: “an octal number follows.” Much like 0x indicates a hexadecimal number.

So a little silly, a little serious.
