It's not a change AFAIK but a bug, additionally I've only experienced this issue with a particular model of Strelas, nothing else. ED can't make everyone happy but I think they've done a great job with FC2. You can take any software and pick it apart to pieces with things you don't like or bugs. I think ED has done the best job with what their aiming for, and for whatever reason I can't think of any other sim that does it better (with regard to modern simulations, there are no others though).
FC2 was meant to be one last improvement to the LOMAC/FC chapter and a way to merge it with DCS-KA50, I think they achieved those goals overall.
