I mean the Devs have said they want people to just play and have fun not do the whole meta build thing and optimal ways to complete every mission and that they will deliberately alter things to prevent that. Also this is giving terrible advice. It is saying Todo main missions first despite the fact that stalkers are such a pain in the arse that if you have them destroying the nests before there are so many they overwhelm you is a must.
Also destroying the spore things so you can actually see- makes life easier and destroying nests definitely lowers the density and numbers of enemies that spawn so…. Up to you if you want to bother but…
