It probably would have needed to be much bigger, yes. That said, the 90 mm f2 does not suffer from such mechanical vignetting it seems, so it may be a trade-off for its macro capabilities. As always, it's a compromise between several factors. It's not the only recent lens that suffer from such swirly bokeh: check the Canon RF 50mm f1.2.
It may be a fact of life when you have the lenses sticking so close to the sensor.

We know that what his name was pretty impressed with the latest canon lenses when he took them apart - has he said anything about the fuji? I forget which lenses have the highest failure rate - for some reason i thought fuji was fairly high.

I remember Klaus having issues with the 55-200 and it was basically not repairable - and I've heard of others with similar issues but perhaps the issue is specific to that one lens.
There was a 55-200mm teardown by by lensrentals here: https://www.lensrentals.com/blog/2016/02/the-long-awaited-scary-and-amazing-fuji-lens-teardown/
