First of all, thanks for listening and replying! Thats definetely not the case for all developer!
Some personal thoughts from my side: A WordPress site has two main tasks: configuration of the site and posting content. Basicly, once a site is configurated, the focus is usually on posting content. I don’t reconfigure or tune my site every day, whereas I post new content several times a day.
So having configuration items in the first line of sight (e.g. top admin bar and sub-entry in dashboard) is not useful for me at all and takes away space that can be used for content production.
My personal opinion would be, having all plugin configuration items as sub-entries within the settings area. I totally understand, that popular and important tuning tools may head for a more exclusive place to be found. So it also might be okay having it at the bottom of the side bar, below but on the same level of the settings link (where your link is also located).
