Mono isn’t going to be used, anytime, by any Linux individual who knows about the whole ‘mono’ war,and it was ugly.
Short story, its not going to agree with the Linux license, and if you need more proof its not legally tenable, then just bing for : mono groklaw.Nuff said 
Oh btw, Fedora threw the whole thing out, in its default setup, and given how huge Redhat is, if that doesnt’ give people reason to pause on mono. nothing will
I know its just for scripting, but it applies nevertheless.
I’m not aware anything has changed in this ecosystem.
YOu used to ‘have’ to get mono from you know where, or it wasn’t considered legal. I somehow doubt much has changed. That was the biggest thing as I recall, the ‘novel’ challenge.
