That's correct. But the only instance of a monolithic exit point in the penalty area happens in less than 5% of games, and if there's a choice – to simplify the game or leave some unplayability – I doubt which of the two is worse.

"I don't play with these templates, but you still can't touch anything there!"

There's another position. "Let's create templates with a billion zones and a size of XXXXL and complain that the game generates them incorrectly." I'm sure that the templates weren't even tested during creation (as with maps/templates in any game).
