I think for guys who were already diligent about formation subs & personnel groupings, which was the primary way I competed in CFMs on defense, this won't change much to your point.
I have at least one nickel set, for instance, where I'm playing a 3rd safety in the slot instead of a CB and generally have run-stuffing personnel in at the DL and have little to no blitz plays as part of this package, specifically for the situations you're talking about, where the offense comes out in 11 personnel on 1st down. It's very common both in Madden and in the NFL. So for guys like me, and I know there are many here, this doesn't move the needle a lot other than probably saving some time, as for many pass rushing formations we'll already have the guys we want in. But we'll still have to go in and make some formation sub tweaks or what-not.
Where I think it helps is the out-of-the-box guys. I know we have otherwise solid players who don't like to mess with personnel & formation subs in our league, and we have a super active league. So this helps those guys. People are free to agree or disagree whether that's a good thing, but I see it as overall a good thing as personnel becomes more realistic for guys who don't want to mess with it.
