I believe the questionable legality also extends to any kind of video calls taking place on systems with this turned on.
If Recall indeed "does not perform content moderation", then having it on would include having screenshots of all video calls.
Especially in many-party consent jurisdictions recording video calls by taking screenshots at a sufficiently high frequency without the explicit consent, or at least option to opt out, of remote parties is probably illegal.

Disclaimer: IANAL and this isn't legal advice.
