TrustExecutor Termux by itself is kinda old and dangerous app, not talking about its repositories that are almost always connect to .cn servers
Syncthing is a FOSS file sync cross-platform app that is now retiring it's Android apk version leaving only cli linux-based app version that can be used only under Termux atm. Syncthing allows sync of files between nodes without involving cloud.
So one could, for example, sync contacts (address book .vcf) and calendar (.ics) within others without any cloud infra (even self-hosted).The same goes for KeePassDX backup to other people in encrypted manner. Or backing up your digital archive to any "permanent" storage.
All of that relies on unsafe Termux. Having it migrated to native environment would be great.
Not speaking of Termux limitations, like inability to be run in non-owner profile, etc
