I definitely wouldn't want to use any models that was made with booleans unless the mesh was cleaned up after. Ngons and stuff make it real hard to do any editing on the object unless it remains procedural. Sooner or later everything we do in Blender will be procedural anyway. Its going to be 100% node based after version 3, even the modelling. I'm not sure I like that idea, but that's where it's heading. I heard some people saying Blender will soon be like Houdini... all nodes for everything. Extrusions, bevels, insets, everything will be done through nodes just like the materials are. Only sculpting and some character animation will remain hands-on, but most animation will be through nodes too. Not sure I like that idea.
