Do Unity Registry addons increase build weight?

Question

Unity

I always uninstall Unity add-ons that are unnecessary in this project through the Package Manager (not My Assets). Does it reduce build size?

Answer 1

Technically, if there are no links in the editor and not in the Resources folder, then the asset / code does not get into the assembly.
You can specify what exactly got into the build and sizes in BuildReportInspector .
