Are these new T2-based Macs usable with Linux yet?

Honest question.

Edit: For the downvoters, it’s a real concern: https://www.idownloadblog.com/2018/11/06/mac-t2chip-linux/

It is not, and it won't be in the foreseeable future.

Patches have been posted to the linux-nvme mailing list adding support for 2018 and newer Apple NVMe. It looks like there are two main ways in which Apple's violating the spec, both of which can be reasonably handled by adding device-specific quirks to the driver. I expect these patches to be cleaned up and pass review in time to be shipping in stable kernels before the end of the year.
