Wouldn't having a gap a micron wide be enough for casting the spell?

It's not a mess - it's very clear.

I'm not sure why you would intentionally misinterpret the rules in such a broken fashion (Resilient Shere, in particular, becomes an incredibly broken spell with your houserule).
Ratama, I know you're new here, but you might want to lead off with a little less insulting manner - even when you totally think people are wrong.

No.
The area of the gap has to be a square foot.
