Comment:

 Using `register_meta` as a whitelist does seems like it'd be the way
 forward.

 Perhaps something like

 {{{#!php
 register_post_meta( 'post', '_my_meta_key', [
         'show_in_rest' => [
                 'allow_querying' => true,
         ],
 ] );
 }}}

 We'd need to decide how much customization we want to allow as well. For
 instance, I imagine the collection param schema would default to the
 existing schema. Do we want to allow customizing that schema as well? It'd
 allow for things like only allowing querying by certain values.
