But there's one huge advantage of retrofocus lenses - telecentricity.

Even when designing a telecentric lens for mirrorless the designer has the option to put correction element closer to the sensor.

usually it's a group of elements yes.

For example the EF-M 11-22 is a telecentric lens with a rear element that would be hit by a DSLR mirror.

In a recent interview Canon attributed the exceptional performance of that lens to the design flexibility given by the short lens register.

Fewer design constraints = more design options.

yes, but also depending on the sensor there is more design constraints with mirrorless.

consider the problems being found with the FE 35/2.8 with circles around the sensor.  sensor reflections with some lenses with the A7,etc,etc.

the fact that alot of MILC cameras modify raw output to handle color shifts,etc - and must do that to maintain any reasonable output.

so while the pure theoretical optical design may be simpler, there's no free lunch as the sensor size  and/or pixel density increases.
