The main issue I have with this is that, like you could guarantee vi/vim being present on any Unix/Linux installation, mspaint.exe would always be present on any Windows installation for easily taking screenshots. When working with locked-down systems, such as we do at work, that was a really useful feature.
AltGr+Scroll, Win+R "mspaint", Enter, Ctrl-V is in my muscle memory.
Snipping Tool still there for screenshots.
Can't capture a mouse hover with snipping tool.
You can if you use a delay.
Second Greenshot. It satisfyingly solves "turn a specific part of my screen into an image" as smoothly and simply as well as is probably possible.
