To me it’s more troublesome for the designers and developers to get rid of js function in a child theme that inherits everything from the default.
As a designer / developer surely you know what can happen with progressive enhancement. P2 is a fine example of what a developer knows. I mean the new 2010 WP theme doesn’t come with js does it?
I like to grab it, dig in, or build from scratch. Now with the default theme inheriting a whole lot more it sometimes is a pain.
Why am i complaining this is one heck of a free meal. :p
