Drop this and use the EDALIZE_LAUNCHER environment variable instead. There is an upcoming refactoring that, among other things, will standardize this for all the backend flows

I will look into it

The new options look cleaner, but I'm worried about current users of the xcelium backend because removing the old options will break things for them. Or do you mean that the xcelium backend didn't work at all before? In that case I guess there is less risk anyone will complain

unless someone would use the generated make as standalone without the generated file list - the previous backend did not work.
so I think it is safe to assume that no one used it.

Use the logger instead of printing to be inline with other backends
