So How Good is the Sigma 10-18mm F2.8 DC DN | Contemporary?

How effective IBIS is depends on the focal length.
It is generally not great at 10 mm but it is less needed.
It should be fine at 18 mm.
Gordon Laing from Camera Labs usually has good tests but as he says "Your results may vary."

there's always the string monopod for those times you can't use a monopod or tripod.

I always carried that gizmo in my bag, handy at times.

Because we are losing some wide angle, thanks for Canon's decision to use a smaller APS-C sensor.
I think it is a little bit strange to complain about a format based on APS, that Canon introduced in the film days in 1996 to EF (EF-S) mount.
Others (Nikon users) could and maybe do complain about the fact that they "lose some tele" at the long end because they prefer that end of a zoom as they are birders and wildlife photographers.
Canon's decision with APS did set a standard years/decades ago.
And I can't see a "this is better" and "that is worse". It's just about choosing the tool that works best for you.
If WA and UWA is important to you, chose the lens with the FL you need, or maybe even switch to DX or FF if that offers you better tools.
Sorry, but I don't get your argument.

Canon already had APS-H so it made sense to have a larger crop for APS-C.
APS-H was introduced in the digital era, APS before that in the film era.
Personally, I was no friend of APS back those years. I always preferred FF/135. But that's the history of it.

At Canon, APS-H was introduced with the EOS-1D in Feb. 2002, after (!!!) APS-C (Aug. 2000, EOS D30) but before the first FF sensors (Nov. 2002, EOS-1Ds).
So IMO, APS-H was just an "intermediate step" or an answer to Nikons DX format, until they could make FF sensors in a good and cheaper way. (YMMV)

So at Canon, APS and APS-C were always first before APS-H.
But not before the DX format (Nikon D1, 1999).

Something weird is going on with the size comparison picture:

The Sigma sits way too far to the left of the camera, and looks to have been scaled to match the width of the canon 10-18.

Edit: Looks like they've already updated the comparison image: sigma looks even smaller now:
