Unity + Appium + AltTester support

We have a Unity game, and we implemented a few
scenarios using AltTester, and that part works fine. We have some
other questions: we want to integrate it with Appium and we are using
the plugin with:
appium --use-plugins=altunity

However, this plugin is compatible with Appium version 2 and does not
support version 3. Will it support Appium 3 in the future? Depending
on that, we want to decide whether to integrate with Appium. Or any other suggestions?
