How can an encrypted backup be incremental if it's supposed to be never decrypte...

Why would you need remote data to create an incremental backup?

I'm sure if borgbackup can pull this off, Signal can, too?

The solution is to split up your data into encrypted chunks, and only upload the new ones.

Why wouldn't it be possible? All it really means is that you need to do the work to make incremental entirely on the local side and not on the remote side.

That seems pretty trivial to implement

I dare you to implement this then, where others have failed.

tar --listed-incremental=foo.snar -cf - . | gpg --encrypt -r <key> > nightly.gpg

You're welcome.
