Seems a bit arbitrary that the pref is registered here and not in a location
closer to where this is used. Is there a better place for the registration to
live?

I can put it in c/b/ui/browser_ui_prefs. There doesn't seem to be anything
closer to the settings page. (Done in this patch)

There could be a case for c/b/profiles/profile_state.cc, although these really
are UI and Settings related Prefs, moreso than profiles.

Otherwise I can create a new RegistryPrefs method within c/b/ui/webui/options,
likely within OptionsUI. I'll defer to you as to when it's warranted to split
off a new home for registering prefs.

I think you should put them here:

Chatted with noms - she agreed.
