This would be a good idea to reach new users. There are already a few other browsers on there such as Vivaldi and Opera, and I think Firefox should be an option for users too.
I agree with this. I recently acquired a Huawei Phone since my old phone (Samtaesong) broke.. left my launch codes, very bad. Brother Xi gave me a new Huawei though!
Only alternative I can think of due to lack of AppGallery is using F-Droid, or Aurora Store - the latter being more convenient since it's literally a FOSS client for Google Play which means instant updates for Firefox in line with Play Store releases.
