Comment (by edge22):

 Just wanted to chime in here about the deprecation notice.

 As we saw with the `_load_textdomain_just_in_time` change in 6.8, a lot of
 users have `WP_DEBUG` enabled without realizing it. That update caused a
 wave of confusion and support requests from everyday users who suddenly
 saw warnings in their logs or even on the frontend:
 https://wordpress.org/search/_load_textdomain_just_in_time/

 In my opinion, `_load_textdomain_just_in_time` was a necessary notice - it
 revealed a real problem that could lead to incorrect translations.

 In this case, though, the IE conditional change doesn't seem to expose the
 same kind of breakage risk. The notice could end up creating noise and
 unnecessary confusion for end-users without providing meaningful value to
 developers.

 Maybe it's better handled silently (or logged only when `SCRIPT_DEBUG` is
 enabled), instead of surfacing as a `_doing_it_wrong()` notice.
