Hello Jiri,

you mentioned WSL. Isn't that still more or less beta? I would expect
that it is very hard to activate that in some company environments. The
same is true for Virtualization or cygwin. I think a lot of developers
are dependent on what their companies IT allows. So it is always good to
have as much options as possible.

On the other hand most of the time companies work with a specific BSP.
Although sis is incredible useful for a lot of cases it isn't a
necessity for all users. So I'm personally not strongly biased for one
side or the other.

Best regards
