I'd like to chime in here because I also think that we should be able to boot (recovery) images with fastboot. I just installed Magisk on my Pro1, using one of the boot images from the forum. But I only did so out of desperation. These boot images are blobs and I cannot control what is flashed to my phone. I would have preferred to boot TWRP and install Magisk directly. The Pro1 not letting us boot or flash recoveries is actually a big disappointment to me. And I lost some hours trying and failing, before I found out that fastboot is restricted on our phones 🙁

Yes, I managed to install Magisk on that build. I had to install two OTAs first, to get to that build.

I am in a similar situation, my build number is 20191203104303 ... As a side note: I tried booting TWRP and installing Magisk directly, but fastboot fails with "FAILED (remote: 'unknown command')" 😭 I tried on three computers, using Windows 10 Pro and Server 2016, and the latest platform tools from Google. I also tried different ADB drivers, including the latest universal drivers from Google. The only command that runs successfully is "fastboor devices", which returns the device number of my phone, as expected. No other command like "boot" , "reboot" or "flash" seems to work ...
