Re: how is this better than Cygwin?
"You do need to be on a 64bit version of Win10 or Server2019 though."
And this _is_ the dealbreaker... (I assume Win-10-nic 'Home' also cannot run it?)
re-compiling for cygwin already happens, as it has its own package manager in the form of the 'setup' utility.
Running native Linux applications is interesting, but less of a 'thing' with me. I would consider overall usability to be the number 1 feature. I messed with SFU/SUA/Interix years ago, and it just couldn't perform better than Cygwin.
I would expect WSL to be similar, regardless of the bell/whistle/shiny factor.
(that and I can run Cygwin on a Win7 box)
