I'm worried that pushing whole-disc encryption at people who aren't aware of the consequences is a huge risk.

I suspect for most consumer and small-business users, the risk of "a power surge blew out my motherboard and TPM, but I can take the surviving SSD and plunk it in a new PC and salvage my data" is a much more important use case than "someone might steal my PC and get at my valuable unencrypted data." I know we've heard people screaming about this on the MacOS side, but thereit's intertwined with the unrecoverability of a soldered storage subsystem.

Large and technical organizations who might need the encryption are hopefully more likely to have IT staff and policies for backups and recovery, so they'll be able to handle that emergency better.
