Ah yeah, the deluded (you) thinking everybody else are the insane ones.
If you look back at that time period, the "Fine!" surely came about because iPhone jailbreakers had extracted the API from the apps and were making their own Cocoa Touch apps and sideloading it onto the iPhone. "Let's enable" sounds like they decided to open it up to the public, if your theory about stop-gaps is correct I would've expected the wording to be "Fine, let's enable CT apps early.". The rest of the email also talks about the jail which is the app store, which seems to be a rough concept of "What we need to make this happen", rather than something that they've been preparing in the background.
It looks more like you're having a stockholm syndrome with your own "knowledge".
Cocoa Touch apps wasn't a new idea, since that's what all of the Apple-developed native iPhone apps used. What's new to this email is getting approval for enabling 3rd parties to write & release them without jailbreaking your phone.
