They don't need to endorse Asahi to endorse the use of alternative OS on ARM Macs, which wouldn't have any of those downsides. The first Intel Macs were great machines to run Linux on. Later machines had too many compatibility issues. From that experience I'll steer away from Macs as I have no interest in OSX and don't trust them to not break Linux. If they publicly commited to alternative OS friendliness that would go a very long way for me.
If the bar is just supporting the use of alternative OS's, they've already done that.
Craig Federighi (their SVP of software) mentioned that support for other OSs is an explicit goal of their boot setup in interviews.
Is there another interview that goes into the details of Apple's boot setup goals?

In this one, Craig Federighi says “We’re not direct booting an alternate operating system. Purely virtualization is the route. These hypervisors can be very efficient, so the need to direct boot shouldn’t really be the concern.”
Allowing booting other OSs is different than actually supporting those efforts with documentation for example. The problem with Intel Macs is not being able to boot another kernel it's all the device support that's now gone.
The fully documented BootPolicy system, all new to M1 Macs and not found on iOS devices, explicitly supports running your own kernel on these devices. It’s also supported by new tools for implementing boot code. Apple has clearly devoted a lot of resources to this, as the Asahi Linux team have repeatedly pointed out.

It's different with Apple Silicon because their hardware is more differentiated; meaning it might be more interesting for them to see non-macOS usage for it.
