Good to know about the obviative case, that there's a name for these type of things.

When writing docs in code recently, it struck me as a little odd that pronouns can be used as a shorthand when referring to a singular and a plural, but can't be if they have the same plurality.

E.g. "When the name and errors exist, and it is non-empty and they are capitalized, ..."

Speaking of Japanese, I learned from that friend that they don't use 2nd or 3rd person pronouns that much at all, preferring to repeat the person's name. For third person it's strange to my ears, but it was very surprising to hear my name repeated in second person!

Yes. 2nd and 3rd pronouns tend to be harder to use in social contexts.

You usually convey a bunch of info and intent when referring to someone (how close you're to that person and their social position relative to you), and pronouns don't easily cover that range. It can be done but requires more finesse.

That's perhaps why pronouns are so tainted (You=anata has become the most stereotypical way to call one's husband)

The better choice is usually to omit the subject and just imply who you're talking about. Using their name is the second best alternative.
