I've only heard of the dark age of compatibility. Supposedly that was an issue in the 90s. Interestingly my only Sigma lens is from the 90s but it worked well (compatibility-wise...) on every Canon body I've tried it on, from 20D to 1DX. The EF to NZ adapter required a firmware update though. 
I've often been asked by colleagues why I, a known Canon shooter, suddenly turned over to Nikon mirrorless instead of Canon, and even adapt EF lenses to Z9 (in fact, both familiar and unfamiliar photographers have been stopping me during the Economic forum to look and inquire about this setup) instead of buying into the RF system. I answered that I'm seeing RF as a dead end trap I don't want to fall into.
