Ok, I will try with migrations inside the plugin and see how it goes. My main concern with plugins shipping migrations is support requests. Right now, uninstalling a plugin removes pretty much all traces of it. If we start encouraging migrations inside plugins, uninstalling the plugin won’t necessarily fix the problem.

As long as plugin developers don’t modify any core tables, it should be reasonably safe 🤞.
