It's bootable, every macOS release has it's quirks and limitations - only High Sierra supports everything.This is really interesting. So even though their FAQ says it's not bootable, it will be bootable with a single drive? So for example, I could have a single 15TB boot SSD drive, and then use the other 3 ports to do a software raid with 3 additional drives?
That's great news then! I wonder why they don't update their FAQs...
Since it's a very complex subject, they play safe.

Yes, you can. No one tested with drives bigger than 4TB that I know of.
