Didn't say it was essential. Just that I would prefer it.
As you said, "nobody in their right mind" would do it. One of the hallmarks of
a well-designed language, IMO, is that it doesn't silently allow you to do
things that no one in their right mind would do. At least a compiler warning
would be nice. I couldn't begin to estimate how much time this compiler warning
has saved me:
Warning: Assignment within conditional. Did you mean == instead of =?
Do I make that mistake frequently? Not really. But if I make it in 1 out of 500
if statements, given the amount of code I crank out on a daily basis, it's
going to happen now and then, and the time the compiler warning saves me is
significant.

It would be nice, but it's hardly essential. It's never going to be
good practice to put in multiple commas and I can't ever remember
have issues doing it accidentally.
Raise a bug.
