In most scenarios it is definitely good-enough but even in just my own personal experiences over a decade I need to asterisk all three of your listed benefits.

True. But Docker comes with a lot of complexity. And it comes with a meaningful performance hit on macOS and Windows. And it doesn't work at all on Android/iOS.

It's so sad that running software on Linux is so wildly complicated and unreliable than things like Docker had to be invented. :(

For most uses wsl2 on windows is pretty close to a bare metal instalation

wsl2 runs under the windows hypervisor as a vm, but so does windows since windows 11. So there should not be much performance issues from running stuff in windows vs wsl2. The major bottleneck is if you need to move files from and to the windows vm to the Linux vm

My interest in running Linux binaries on Windows is zero. I run native windows binaries. Why would I want to run via WSL2 when I can do it natively?

Why people constantly insist on adding unnecessary layers of abstraction is beyond me.

Nobody is forcing you to use anything I just wanted to underline that the performance hit you mentioned is not really there, as we are in a public forum there is value to keep things factual.

As for why to do it, if you develop on server apps Linux is the standard (as an example redis does not have a windows native version), and I say this as a developer of Windows based microsevices on the cloud, my company is actively looking to migrate to Linux due to lack of tooling in the windows space (and also licence cost of windows server), like it or not that is the way it goes. If you don't need it great for you, but for other of us those layers are life saver
