The unix philosophy of simplicity was on a per tool basis, not function or line of code. The walrus operator is Python version of what we can do now in C or in JS, doing plain assignment in an expression while evaluating it for truthiness. And more often than not, the point of that single-purposeness in Unix is so you can chain a bunch of piped commands that result in a perl-like spaghetti command that's three terminal widths long.

no, it evaluates to the left side's value after assignment

Well, yes, that's right: the return value of an assignment expression is the left side's value, which is what makes the assignment/evaluation work.
