> I also think there's different use cases than an ssh app. If you just need an ssh app, then why even bother with Termux (because .ssh/config is a pretty well known is somewhat of an answer but still doesn't require termux).

You still need to run your ssh client somehow, and last time I looked termux+openssh was straight-up a nicer experience than anything else I could find on Android (which I always found funny, but there it is).
