the development of more advanced 3rd party mirrorless lenses?

I just watched an interesting review of the Nikon & Tamron 28-75mm f2.8lenses, where the question was raised whether the "smaller size" of the Sony E-mount was restricting the development of more optimal or advanced 3rd party lenses for the larger Nikon Z or Leica L mount ie. Sigma lenses for the L mount are constrained by being designed in parallel for Sony, rather than being natively designed for the L mount.

Curious as to your views.

Interesting, but Sony has some great lenses so on the surface, it doesn't appear to matter all that much. I don't know that Nikon or Canon have any lenses that couldn't have been made for Sony, or at least ones that anyone would want to buy(thinking about the nikon 58mm NOCT).

I think Sony has proven this criticism of the size of their mount to be wrong, or at best, just a bit more challenging for lens designers multiple time.

Maybe the design of the sensor relative to the mount? See the bokeh section here:

That article makes no sense, there is no physical difference between the Sony APS-C and full frame mount, they are absolutely identical in every way. It is exactly the same spec - Sony E-mount. It's only the lenses that project a full frame image circle that are designated FE, there isn't an FE lens mount. The lens test is for an APS-C lens while the debate about the Sony mount being limited due to its size is all about full frame lenses and designs.
