I believe so. You'll need to disable CT enforcement / or add your SPKI hash to the ignore list in the browser settings temporarily to get it working. [0] I guess this is also how corporations get around this issue? Still unsure.

No. CT is only required for public CAs. You only need those browser policy settings if you’re using a public CA without CT.

I'd imagine this is why certs that terminate in root certificates manually added to the trust store will work fine then [as stated by other comments]?

Right, any CA you add yourself that isn’t part of what Mozilla ships isn’t considered a publicly trusted CA.
