Would you concede that there could be a security diff between JIT and not JIT?

All Gruber is arguing is:

1) that there is a significant difference in security

2) that Apple didn't release any JIT for webkit all this time [edit: since 2008] because of security concerns

3) that Apple did not go out of its way to remove JIT from those instances of webkit that occurr outside of Mobile Safari

4) that perhaps Apple is simply rolling it out gradually

I don't see how any of this is ridiculous or could be called "bending over backwards" unless you are pre-loaded with a bias against Gruber.

There goes what little karma I earned since 2008.
