It is then up to each process to handle preference modifications and

is done unfortunately.
Will SpecialPowers.pushPrefEnv(), which currently does propagate the
prefs at least between the content and parent processes, continue to
work? A lot of tests rely on this.
Preference changes in the parent process are automatically
propagated to any child processes that handle preference
changes. Currently, I believe that does not include GPU and VR
processes. It does include web content processes and the necko
process.
But for processes that do propagate preference changes, it
doesn't matter whether they use StaticPrefs or another
preference access API.
