Why do some versions of Flash Player require a new DMG to be downloaded through a web browser?

Why do some versions of Adobe Flash Player require a new DMG on OS X to be downloaded through a web browser? It is an annoyance to users to have to go through downloading a new DMG and installing through this method. Why can this not be an in-place download and install just as the normal delta updates?

In addition, is there no way for Adobe to implement a new update process where the browsers are not required to be shutdown if a person is updating? It would make more sense to put things in place for the user and have these new values put into effect when the browser is finally shutdown. Unless the browser is shutdown, whatever version is already installed and running will continue. Is that some sort of privacy problem for Adobe?

First point: I don't know why they don't just have the PKG file for download, other than it's harder for unscrupulous folks to make a DMG that will pass the "Gatekeeper" checksum.

Second point: Since the browser uses the Flash Player Plugin, trying to update it while the browser is running would be akin to trying to change your oil while driving down the freeway at 70MPH. And then there's the whole "admin password needed" thing, that would prevent "blind updates".

You can always download the offline installer: Flash Player (For Mac OS X) and run it whenever you want.
