I have no idea what you're talking about.
We're talking about the RF 50mm f/1.2 vs. the EF 50mm f/1.2. The EF 50mm f/1.2 came out in like 2007 and you're talking film and sub-10MP sensors?

I have no idea what you're talking about, either.
What I actually said (which you couldn't even include to the first comma because it weakens your depiction of what you want to pretend I meant) is, " People were not as concerned about resolution back then
to the degree they are now for a variety of reasons..."
I also said, "For non-Macro lenses, people also were not nearly as concerned about resolution
at the edge of the frame when the lens was wide open and focused optimally on the center of the frame
as they were about resolution at the center of the frame back then."
So please stop pretending I said no one cared about resolution at all without any qualifications.
The EF 50mm f/1.2 L is a
classic double Gauss design that has been around for far longer than 2007, even if that is when this particular lens using it was introduced. It's basically a minor modification of the Taylor, Taylor & Hobson Series O f/2 designs from 1920. The fourth and fifth elements are a group that acts in the same way as the fourth element of the TT&H design, and the sixth and seventh elements are a group that acts in the same way that the fifth element in the TT&H design does. The only real modification is the use of a single aspherical surface in the final element.
As Roger Cicala noted in the blog entry linked above, "It’s also not surprising that each of the 50mm lenses have some characteristics in common (wickedly sharp in the center, a bit of field curvature, a bit of edge astigmatism, etc.)." If you want to argue that the EF 50mm f/1.2 L is not sharp in the center, argue with Uncle Roger.
In January of 2007 when the EF 50mm f/1.2 L was introduced, the current cameras in Canon's EOS lineup included:
8.2 MP 1D Mark II N
12.8MP 5D
8.2MP 30D
10.1MP Rebel XTi/400D
16.7MP 1Ds Mark II
The 10.1MP 1D Mark III was introduced later in 2007, as was the 10.1MP 40D.
