I fully understand that Microsoft does not set the GCC compliance standards, but they are the ones that have to ensure their products and services are compliant with them. It is on their shoulders to ensure that features they release are compliant with the mandates set forth by whatever Government bureaucrats.
This is not a new process to them. In some instances, the features they release are immediately compliant (which is the goal, for some of the teams I've spoken to). In other cases, such as this, there are long standing features that still not GCC compliant, even if they control some of the more critical aspects. E.g., It makes it harder to push for conversion to things like WUfB when you do not have access to the Quality Updates feature to push an update "Right meow" because your knee-jerking SecOps team is freaking out and dry-heaving into paper bags after the latest alert.
Either way, this particular line of discourse is irrelevant. It is entirely upon them to make a feature compliant with mandates, be it FedRAMP High, CJIS, or IRS 1075, to name a few.
If they have an answer, or even a "Hey! We're aiming for Q2 of `25," I'd love to hear it.
