I sort of agree with some points, especially the ones about dynamic identifier creation and renaming identifiers, but those last 2 to me sounds a lot like you don’t know how to search beyond the really basic “I want this string here”, I’m assuming that it’s an effort to enable whoever comes next to search and find everything they should find mindlessly, not knowing the project, since the author talks about navigating foreign code bases, but I think compromises can be made when you should expect just a bit more effort from contributors for the sake of a more rationally organised code base
It’s really about lowering cognitive load when making edits. It’s not necessarily that someone can’t figure out how to do something more sophisticated, but that they’re more likely to get things right if the code is just kind of straightforwardly dumb.
The last two are definitely situational – changing things like that might lower cognitive load for one kind of work but raise it significantly for another – but I can see where they’re coming from with those suggestions.
