I wouldnt mind a bottom bar if it would:
- Ease multitasking e.g. through swiping left/right to switch between open apps. With a bottom bar you would not have to use edge swipes like SailfishOS, Ubuntu Touch and Android 10 (which imo is the worst with the bottom handle).
- Allow closing apps/dialogs etc easily
And of course the current use case of bringing up open apps + launcher
