Comment (by peterwilsoncc):

 Replying to [comment:6 hellofromTonya]:
 > It might be a doing it wrong or potentially a case for further defensive
 coding. Thus, the `php-compatibility` focus should not be added to the
 ticket.

 I think this is similar to #56311 in which site visitor input via the
 URL/form data also triggers a notice (in the other ticket's case, it's an
 out of range week, `example.com/2022/?w=506`).

 I think it's a case in which a bunch of defensive coding needs to be added
 to the `WP` class to validate data before sending it to `WP_Query`.
 Throwing a notice in those cases isn't helpful to the site developer as
 they have no control over visitor data submitted via a URL.
