I'm personally planning to replace termux with a full chroot; my phone is rooted, so all I need is an app to give me the actual terminal emulator and I'm good. This would be fine for running the odd Go utility, but is likely to be insufficient if you're doing anything with the actual Android API (which termux has been great at). And of course, in the long term this is just another reason for me to hope the pinephone gets to prod-ready ASAP:)
