It's literally never been an issue for me even when shooting with the 35/1.4 in bright light. The electronic shutter goes up to 1/32000s, you can shoot in as bright of light as you want with it.
My decision might have just been made for me... one of my good friends says he'd be very interested in buying my a7S if I sold it... the reason this is such a big deal is that he and I share our camera gear all the time, he borrows my lights, I borrow his go-pros and even 5Diii occasionally. I told him I'd give him the camera for $200 less than the cheapest one he could find so long as I could use it a couple times a year (for astro or low light work), he said he'll let me know soon... I'm still not positive I'll do it, but man is it tempting especially since he never sells any of his gear.
We have different but entirely valid values about ISO as photographers. 
For me a base ISO 200 is problematic as it limits dynamic range and introduces a touch more noise than 100. Add to it that the XT2 is an APS-C sensor - inherently more noisy/less DR than the same sensor tech in FF - and it's too many strikes against it for me. But, my work largely differs from yours in that my focus is largely on detail-intensive landscapes, cityscapes, architecture, etc. For those subjects I am highly noise-averse.
However, if my photography focus was more in line with similar subjects as yours I could absolutely see the notion of dumping a FF setup and going all-in with the XT2. Also, I think it would make a phenomenal street shooter (excellent IQ + small/light + superior controls).
If there was someone who could convince me otherwise it is Locardi. However, since I have his training series on Cityscape photography, I have seen his use of the XT1, which he used in tandem with the D810. I was able to see his XT1 files next to his D810 files...it wasn't convincing at the time (and he wasn't convinced either or he wouldn't still be mostly using the D810). If he dumps Nikon and goes all-in with the XT2 then that will definitely capture my attention.
Regardless, his XT2 cityscape captures look phenomenonal, so I am not discounting it for my use...will definitely give it some thought. I could sell my 5DS R and a couple lenses in order to fund an XT2 with some quality lenses.
