For example, why not introduce gendered nouns - they often help to clarify references? "The door and the window are open." - "Well, close es (=das window)" vs "Well, close sie (=die door)".
Other languages indicate evidentiality (that is, how a speaker learned about something) by a verb suffix, eg Eastern Pomo:
* -ink’e (nonvisual sensory), * -ine (inferential), * -·le (hearsay), * -ya (direct knowledge)
Now, I might say, in English that is clear from context, or expressed in some other way, but according to you, "we should avoid it if we can". Thus, better learn Eastern Pomo?
I might do. But I don't wish to add my static preconceptions upon an evolutionary evolving thing like language and its linguistic community.
That said, I speak a language with gendered nouns, and they're fine.
"Bring the table", "Bring a table".
Do I ask you to bring some table we've already talked about or I can expect you to remember the reference to,
or do I ask you to bring any table because any table will do?
"Clear from the context" is a low bar. In languages, as in parsers, we should avoid it if we can.
