Perhaps, but compilers for many single-vendor non-PC platforms certianly could supply this information. It looks like the RM had just this in mind, with compilers for PC's and some platform "families" being forced to use the weasel words. Additionally, I could see where the the disctinction between the two kinds of drift could get really blurry on platforms where Calendar doesn't have OS support. Even when the platform's drift isn't known, I could still get an answer like "0 + F, where F is the clock drift of the hardware", or "10 + F + G where F is the clock drift of the hardware in seconds per month and G is the clock drift of the underlying operating system in seconds per month".
