That approach is a little meh ...
It's really astounding that Sigma doesn't jump on the mirrorless wagon really.
The days that mirrorless cameras were exotics are long gone by now.

9 AF primes is "meh" to you? Feel free to kickstart your own design of AF lenses. Like Tamron, Tokina, Voigtländer, Laowa - whoopsy: No other brand comes up with new designed fast and affordable AF lenses? Don't they want to jump the Sony waggon? How come?

I'm sure you are aware that
- these are no dedicated mirrorless designs this just adding a spacer is a little cheap
- the AF motor is DSLR centric - works well with phase detection AF but crappy with contrast AF.
And whoopsy ... why can't Sigma do what Samyang can ... :-)

The AF - at least what Sigma claims - is changed to the needs of mirrorless. So it's a bit more than just a fixed spacer, but if I were Sigma I would go the same path: The lenses already are big, heavy and good. More distance to the sensor is a good thing in terms of corner vignetting, I think. Developing a new set of lenses, although there is no FF mirrorless from the big 2 would appear to me as economical bullshit, sorry. If samyang wants to dedicate themselves to Sony bodies, have fun - they already are new kid in town if it comes to AF lenses, so why not start with what it's available.
But Sigma's hesitation I understand fully.

FWIW, Sigma claims to have improved the algorithm - thus it's not about new AF hardware.
