> It seems like a nice way for an author to be able to express much more meaning in the exact same number of characters.
Quite the opposite: It damages beyond repair the ability to pick out proper names at speed.
English has a horrid habit of re-using common nouns as names. The miller John becomes John miller, not John Miller.
Worse, the proliferation of brand names means that readers depend on capitalization to know if they are talking about, e.g., google, a common generic term for searching, or Google, the Alphabet (not alphabet!) subsidiary.
So, under the new regime, authors get to be more precious at the expense of their audience's time and concentration.
That's a Nope from Me, Dawg.
