I’m going to repeat my questions from the stream as they got misinterpreted. Hopefully someone can help out.

1. Do engine plugins need to be explicitly disabled to not be linked?
   If someone uses one of my plugins in their project, most likely they will make use of it via types exposed to blueprint and not add any dependencies in their .build.cs files. Nonetheless, my plugin, assuming it’s enabled, will be packaged and linked into their game. So, since many engine plugins are enabled by default, does this mean that they are all getting linked to a project executable even if they are not being used? Most projects won’t use most plugins, so if this is the case it would be a pretty big unnecessary overhead.

When you execute a packaged game of an empty project, the engine does this; so, yep. All the runtime engine plugins are all loaded by default:
