Its not Homomorphic but "structural encryption". Less useful than HE but faster.

Correct. It's not homomorphic encryption, but rather more like TDE (Transparent Data Encryption) except that MongoDB service isn't decrypting the data. This is essentially client-side encryption (at the driver) and without server-side decryption.
Faster has a usefulness all its own
Absolutely! FHE isn't practical for most applications.
