Regardless of how it's done, designing a GUI to accommodate for
the sheer variety of user requirements, preferences and expectations
out there takes a truly incredible amount of effort.

However, CSS 2.1 requires for the following equalities to hold:
72pt = 96px = 25.4mm = 2.54cm = 1in.
When rendering a document for a high-resolution device (such as
a 600 dpi printer), one of the "physical" units (mm, cm, in) is
made true (subject to the user-specified scale) and, e. g., 1px
effectively becomes 1/96 in.
Conversely, for a low-resolution device, 1px is one device's
pixel and 1in is taken to mean "96 pixels" -- irrespective of
the pixel's physical dimensions.

Yes.
The CSS "media query" constructs allow for the parts of the
layout specification to be conditionalized based on the
currently available screen estate, but it still remains possible
for the user to use a screen configuration that doesn't fit
anything the .css author has thought of.
Personally, I just go with the Gutenberg's example and specify
"max-width: 72ex" for the "prose" sections of my Web documents.
(But please ping me when they start printing [non-visual] novels
in single-column landscape!)
