Actually "dot notation" is not easily Googled as such.
Best to search on OOP + "dot notation" or you'll get electron dot notation, Newton's dots for fluxions, other meanings of "dot notation".
Russell and Whitehead had a "dot notation" from Principia Mathematica. The term is freighted (overloaded) with meanings.
What's at issue is not the shortcomings of modeling but various forms of literacy and whether we should share them or not.
Reading music, even just a little, is an eye opener. When you see a piece written for an entire orchestra, you can somewhat appreciate how all these instruments play in parallel, reading from these several scores. Learning to read music helps learning to read other notations.
In chemistry (pre-college) students get used to one and two-letter codes for elements (atoms), then see them structured in compounds (molecules) with angular bonds. More complicated visualizations go with a notation. Lexical and graphical are connected.
"Dot notation" is used in workaday language in a mix with standard mathematics functions, trig and so on. We're talking fluency here, familiarity with cultural lingo, like traffic signs.
Literacy in STEM requires some familiarity with OOP dot notation (ala computer science) in the same way it requires familiarity with electron dot notation (ala chemistry).
Do models sometimes break or are they sometimes bogus to begin with? Sure.
Not all music is equally great either.
Here's link to William Kent's web site and a page about his book:
Lots of interesting musings and speculations, but I see nothing there to dissuade us from sharing more widely and effectively what 21st century math notations include (thinking of computer languages as math notations, ala Mathematica).
