Comment:

 Thanks for the ping.

 Yes, the deprecation notices are intentional (by design) to alert of
 dynamic (undeclared) properties being accessed (see [56354]). These
 deprecation messages will not show in production, only when `WP_DEBUG` is
 turned on as of [56544].

 Before declaring these properties on the class, I suggest first
 researching where in the source code they are being requested? Is the
 request coming from within Core or one of its default themes? Or is the
 request coming from a plugin or non-default theme?
