Msys2 was not created for devops, I just happen to be a devops engineer who uses it. Their websites describes it as:
MSYS2 is a collection of tools and libraries providing you with an easy-to-use environment for building, installing and running native Windows software.
Because it makes software building, packaging and distributing as simple aand standardised as it is on Linux, it means they effectively have a very good CLI on their hands. On my work laptop, I now use WezTerm with fish shell and helix editor for my workflow, and live in the terminal. Would this be possible to do without msys2 or wsl? Yes, but it would be a huge pain.
