Thanks for the clarification and the explanation.

It makes think it might be advantageos to tell IANA that there are a few 
other cities called Los Angeles in the continent America.  They are on 
different time zones.

If so, then the option "America/Los Angeles" could be named
"America/Los Angeles (the most populous LA of America, as of July 29, 
2021); for SF".

I fully agree.

Talking about places is different depending on the respective cultures. 
  If I say Los Angeles to a resident of California, certainly s/he will 
understand LA.  But to a resident of Argentina, it is not sure.

But there are means to accommodate both in a still short name.
