Is Boot Camp still being supported by Apple?
The support site is alive and kicking:

There are no announcements of note relating to this from WWDC 2019 through September 2019. That could change tomorrow, of course.

I’ve moved almost all my work devices over to VMware Fusion FWIW. There are plenty of reasons to not virtualize, so I encourage everyone still in the boot camp - check out Boot Runner - it’s amazing value and super helpful for managing one or more installations. If you have more advanced needs, Winclone Pro (or Winclone) are also available.
