They are 100% not going to develop it any further or support it, but
that is not a problem, existing code will keep working, and if it for
some reason stops working, well, then that's it, then you can and
should remove it. But as long as it offers this functionality for
Flowblade it has value.

I'll look into the compatibility layer, and will give getting SDL2
