I was a dev in the 90s and the start of the 2000s and always had admin rights. I dont need it any more. If you really had an edge case that requires admin rights I'm surprised. If you really need SQL server on your workstation you should think about using a different database. If your company says you have to use SQL server and you have to have it on your workstation and you need to reinstall it regularly and you're obviously screwed you go up the management chain with your unsolvable problem that breaks their policy. Is very unusual now - most people just moan they want admin rights when they can live perfectly fine without it.
It will be really hard to argue for a complete redesign of a medical device app, complete retesting and waiting for FDA approval only because some guy at IT doesn’t like the devs to have admin.
You're basically saying, "I don't need admin rights anymore and can't think of reasons why anyone else would, so clearly you're wrong, don't know anything about your work, and don't need admin rights either".
Try running Visual Studio without admin rights and you will weep. Regarding other rights, I tried to onboard a new Dev without admin rights, however, after the 25th IT ticket (that take days to get done), I gave up.
I run Visual Studio without admin rights every day. But, if you're doing driver development, working with older IIS, certain parts of the registry or developing installers then yeah you're going to have a bad time.
I'm not sure if your "almost ten years ago" is meant to be hyperbolic, or genuine... I can't even remember why, but I know the project I was on 6 years ago definitely needed visual studio to have admin access, and it was all standard C# app stuff (maybe WPF?)
