On top of tagging different layers for a park and its lake not being
"clearer and more accurate", it really is a renderer decision wether
to render a park on top of a lake or vice-versa. For example if your
rendering of "leisure=park" is a very transparent green area, then you
do want to render it on top of lakes and all other features. So please
do not use the layer tag for that purpose.
