I moved over to Godot myself. Not because of anything the company did, but because of constant plugin failures. I didn't burn the bridge, but it just loudly collapsed!
The problem with Godot, and really all the alternatives, is that you have to do everything from scratch. It's a general purpose engine, not an RPG engine. That CAN be powerful eventually, as there's more freedom to optimize, but you end up sinking a LOT of time into re-inventing the wheel on things that are already pre-packaged and just work in RPGMaker.
As for plugins, depends on the one in question. Have to make sure they're for the right version, and yes, sometimes have to do some work to get them to play nice together. As long as you're careful with your stack and try not to make it too massive it's usually fine though. I've also taken to starting to make my own for small things at this point, as it's more targeted, and thus less chance of overlap and conflict with other plugins.
