Hi Richard, I am running 10.15.7 and I think I upgraded to Catalina months ago (but I don't exactly recall when). From my experience, everything works just fine, at least for my current workflow (clients' projects, GHC development etc). At work I have successfully used GHC 8.6.5 and 8.10.2 for various projects, both with Cabal and Stack and didn't experience any major problems.
In terms of performance, I cannot judge. If it got slower, I certainly didn't notice. I hope it helps! :) A.
