That is exactly what using mono-csc gives you. It means that you use the
default mono compiler. The reason we're noticing problems now is that this
switched from gmcs to dmcs with 2.10 and as libu1 wasn't using the default
compiler correctly it was getting 2.0 refs instead of 4.0.

You should use this for your nightlies indeed.

It's not required. mono-csc is more to help ensure that all of our packages
get built for the distro's default profile. But it's backwards compatible:
4.0 apps can load 2.0 libs just fine. Users don't have to care about this.
