> in general people would like their IDE to run language servers, set up build systems, and any number of other things

That I understand, I’m mainly wondering why all that would have to happen automatically by merely opening a folder.

My personal preference may differ here, but for things like running a build or starting a dev server, I usually prefer to trigger them manually, and not have them silently executed only by me browsing through the sources.

Therefore I’m trying to understand whether there are legitimate use-cases for this “auto-run on open folder” feature besides the obvious convenience aspect of saving one or two extra clicks.
