The gawk man page uses "expr1 ?  expr2 : expr3", although there is
also a bit of exposition.

Your idea of who "readers" are and how much hand-holding they require
is not the only idea.

You are talking about the gawk manual, which is written like a
tutorial.  It is appropriate for a tutorial to have many examples.
This is fine.

The bash "manual" is more or less the same as its man page and aims
for concision, like a reference.  The gawk man page is similar.
This is also fine.

Not the same thing.

The "Conditional Expression" section of the gawk manual is about
the ? : operator because "conditional expression" is what they
call that operator.

The "Conditional Constructs" section of the bash manual is about
the "if", "case", "select", "((...))", and "[[...]]" commands.
The operators available within ((...)) and [[...]] are described
