That's really speculation on your part. There may be indications that they will be changing things in the future.

We have work with the VMS people in dealing with some issue that have come up. The Windows version IS the NTP reference implementation. I maintain it along with the Unix version, with help from others including the Meinberg folk. There are a number of other implementations, especially on Windows, but those are really just SNTP clients and it's their poorly thought-out implementation that causes the heavy load on the Stratum-1 and Stratum-2 as well as the pool. There are a number of additional Unix implementations but they very rarely get brought up here or elsewhere. I don't have a list. The exception is PHK's implementation, though we don't discuss that much either.
