I believe you're talking about the perfect telecentricity of Olympus DSLRs but telecentricity (near-perfect maybe) has long been a feature of MFT ever since its inception. As I've said before, their site was heavily dumbed-down but they had all the white papers available before. This link is safe:
The Micro Four Thirds system's greatest appeal is to achieve high image quality, compactness, and lightness for photographers who want to enjoy a camera anytime, anywhere. The open standard means you can use lenses and camera bodies from a range of manufacturers. And that gives you high versatility, operability and usability.

. It talks about telecentricity as its third main benefit.
This is found in the link for those who do not wish to click it:

The statements were referenced to some white papers and even the optical design of the old Olympus 17mm F2.8, which is not known for its performance.

Yes, the MFT lenses' image circle covers that of APS-C-sized Super 35.
Here's another diagram from the link:

It says that it delivers light
almost straight to the light-receiving section. On the four-thirds sensor. The diameter of the rear element is longer than the height of the sensor receiving more telecentricity in the X-axis. The diameter is shorter than the Y-axis and this is where the
almost comes into. Light is slightly oblique at the edges of the Y-axis. On the MFT Super 35 sensor, which is currently being used in filmmaking, telecentricity is perfect in the centre but not in the edges.
Olympus four-thirds DSLR cameras achieve perfect telecentricity because the diameter of the rear element of the lenses is bigger than the sensor itself.
I don't know, It's not as perfectly telecentric as Olympus DSLRs but the telecentricity that we get on MFT is good enough for engineers to call the lenses telecentric.
If we disagree with them, we can always complain to any of these companies:

Olympus and Panasonic created the mount but, since it's an open standard, everyone in the list is part of the foundation, as well.
