Gesture typing is still in early development. The suggestions bar doesn't work yet so it's really hard to use. Nevertheless, looks promising, and it looks like development is starting back up. I'll keep an eye on it.
I have yet to find an open-source keyboard with gesture typing that is anywhere near as usable as Gboard, unfortunately.

A compromise is this OpenBoard fork by Helium314 which is able to use Google's proprietary gesture typing library, which can be downloaded and loaded manually if you want to enable it. It's still a privacy improvement over using Gboard.
