Personally, I think orphans are bad typography and have little to do with pixel perfection. I don’t see why responsive web design necessarily requires bad typography.
Given the tools to address these issues, such as Adobes proposed `text-wrap: balance`, I am sure many would do so.
I thought something like this would been obvious after 2 decades of transitioning from print to web design, but I sometimes still get complaints for things like widows and orphans [0].
