I’ve been using the Dvorak layout for typing and swiping on my phone for many years. It’s actually set to be multilingual, even: I can swipe either language or toggle to Azerty for French (I probably should switch to BÉPO, but I don’t think I have that option yet). I don’t tend to swap phones enough for that to be an issue, and I work remotely so I don’t have to use other workstations, so my use case is probably more suited to this.
