The readability of chaining *is* very subjective. I find it perfectly readable.
Andrea and a few others feel strongly about this, and I respect that.
But most JS libraries have gone the other way, and authors in general
seem to like that direction. This constitutes pretty clear evidence
about which pattern JS devs en masse prefer, and we shouldn't pretend
like we know better than them. In the absence of technical problems
that doom a solution, let's vote with the herd.
