TL;DR
Inserters should not be able to insert modules into beacons and, more importantly, remove them.What?
Literally "What?". "What?" was my first thought when I saw them doing so. So many times rotating an inserter ended up with it grabbing out a module or two and putting them in the belt or getting stuck in its hand.Why?
WHY do you think it increases the value of Factorio as a game?Exactly. WHY this interaction is in the game in the first place? No other entity can interact with the modules in such way, and there's literally no reason to do so. Beacons don't consume less energy when they have no modules, and construction robots (especially in 2.0) can add/change/remove modules easily via upgrade planner (or even Ctrl+C/Ctrl+V).
