Based on how poorly every other Windows on Arm experiment has gone, I'm guessing Apple is not willing to officially sanction bootcamp (yet).
I don't actually know the current status of supported Windows firmware loaders, but the most recent information I had was that even on ARM you needed UEFI with Secure Boot.
I am interested in Linux on those Mac ARM desktop machines, probably takes a lot of effort, I don't see Apple making the effort themselves. On the other hand: there is a super small chance that if the A-series SoCs are marketable you'd get no-OS ARM (micro) servers. That'd be pretty cool.
At the very least, booting windows is a relatively low effort problem to solve compared to everything else that has to happen to move a whole ecosystem to a new architecture. We can conclude its a low priority for Apple, if it's something they still want to support at all.

Apple doesn't use UEFI on their ARM systems, so it'd be an extra effort indeed.

Why assume this would change?
That was a few years ago, there might be better ways of interacting with it now.
It might be worth someone's time to research this area of the economy and provide cross-platform tools.
A lot of people developing apps that run on Linux servers use Macs, and have had MS targeting them for a couple of years as well.
