Indeed, it's a compromise, just like the proposed use of SMS as a method is
a compromise. The ideal is, imho, probably to implement FIDO as a second
2fa measure in addition to the already well-supported TOTP method and leave
SMS off the table, and enforce it on all accounts across the board. I don't
want to let perfect be the enemy of good, though.
