For internal purposes, you're probably right. For distribution and documentation purposes, I think it's much easier to understand "this plugin works on 7.3 or later" than "this plugin works on 2010-08-25 or later."

I think it doesn't have to include fully qualified date. For example, Ubuntu uses date-based versioning, e.g. 13.04

Thanks for pointing that out. It never occurred to me that their versioning is date-based.
