Because we find it to be a perfectly fine term, widely understood and accepted in professional literature.  I remember when most DC power supplies had chokes in them and transmission lines can be impedance transformers (and baluns).  So those terms which you mistakenly believe are more descriptive are in fact ambiguous.

Why don’t we permanently retire the term “balun” and use either “choke” or "impedance 
transformer” in its place?

No its not... it's a choke that many mistakenly call a
Bal(anced)Un(balanced).  Does it act somewhat like a Balun... yes for the
case of a 1:1 but a true Balun can be in other ratios.

[sigh]

A common-mode choke IS a balun.

We're talking about a common mode choke, not a balun/transformer.

Actually that's not true. A lot of baluns are wound with balanced
