mordentral, the creator of the plugin already commented on the thread.
At the end of the day, plugin support is amazing and greatly appreciated, but there are some dangers with using a plugin for a mission critical function of the game. If the plugin author ever abandons the project for any reason and you don’t know how to maintain it yourself, you’re suddenly unable to ever update your engine version without hiring a programmer to port the code over. You’re also missing out on any official tutorial content that Epic may put out, since they won’t be designing their lessons with a third party plugin in mind. And of course, a single person or small team can’t test something as thoroughly as Epic, nor can they always dedicate the time to fixing bugs as quickly as them.
It’s the same situation as a lot of things people have developed as plugins, such as world origin rebasing in multiplayer or VXGI. A plugin, and a free plugin nonetheless, is no replacement for official support. Even if it was Epic just saying “Yes we will integrate and officially support this plugin”, that still carries a lot of weight behind it and shouldn’t be taken lightly.
