I do most of the time when standing or walking, mostly because it's uncomfortable in the front pocket and difficult to get out. I have a Nexus 6, so it's a bigger phone, and no I don't wear skinny jeans. That being said, I take my phone out whenever I sit down. It's second nature at this point, I don't have to even think about it. So no worries about sitting on it and bending it.
I think the south east is the only region that actually implements the cap. It's been "suspended" ever since they announced it, at least in California
Oh, I forgot to mention Netflix. Netflix streams would just drop, or would be slow, or say service was unavailable, particularly at night. Haven't had an issue since disabling IPv6.
Same with Comcast. I tried for a years actually, but some things were too slow. Ubuntu and Debian repos in particular were painfully slow, even on my VMs on linode, digital ocean, and prgmr. I ended up having the servers force IPv4 for them when their IPv6 servers went down for days. Speed and latency on IPv6 have gotten much worse over the last couple years in my experience.
Also, it appears Android doesn't play nice with IPv6. It basically silently drops the connection eventually (I'm guessing it stops listening for the RA broadcasts), and push notifications fail. Happens on Samsung devices and my Nexus 6. So it's reliable either push notifications and low latency site loading, or use IPv6. I finally bit the bullet and disabled IPv6 on the router and all my issues went away.
By default it will use a random privacy address (I believe RFC 4941). So the address will change daily, or every time the device reconnects to wifi, whichever happens first.
I mentioned the +/- zero thing in another comment elsewhere in this tree, actually! So we're all on board there.
It's not really that signless infinity is a contender for 'consensus' inasmuch as number systems which use signless infinity have utilities different from systems that have signed infinities, just like integer math continues to exist despite the 'improvements' of fractions and decimals.
