I would say: the same way that it is relevant to WCS. The Microsoft document
that I have read mentions a "capability for simple measurement-based
profiles with viewing condition tags that can be changed as necessary."

Correct me if I'm wrong, but I take this to mean that profile creation is a
capability directly available within their WCS solution.
That assumption has been made by many. A simple measurement based profile, is a profile that is simply made from measurements, rather than requiring a color scientist to figure best fit polynomials etc, and having fewer built-in assumptions. Measurement based would cover virtually all end user built profiles. Simple is a vague term that appears to be referring to profiles that eliminate the early application of an assumed viewing condition; or it could even refer to the number or location of measurement patches, its not at all clear. Either way this does not mean that a set of measurements will equal a profile.
You could make an arguement that the absolute colorimetric table from the appropriate side of an ICC profile is a (usually resampled) set of measurents, and can be used to generate a simple measurement-based profile; and software can easily enough regenerate a profile from this table, though it probably won't be the same profile that the table was originally contained in. But software is still needed for these processes; WCS plans a plugin architecture were companies can use OS components (such as their CIECAM02 functions) from within their software, to perform tasks like displaying, proofing, previewing, printing, etc...
So even if Microsoft chooses to produce the necessary modules themselves to make profiles from measurements, thats only one route, and not necessarily the one end users will be dealing with if/when they go to build custom profiles. Life as we know it isn't ending, its just threatening to become more complicated...
