How come?

The the adapter will be loaded AFTER the main code, which must not
happen. BTW, I doubt that you can use more then one adapter at the same
time, but I didn't check the extJS docs.

I'm just about to write some code for a custom TCA field that needs to
load extJS. Now what happens if another extensions adds another custom
field to the same table but loads extJS differently.

Even in the BE it is not guaranteed that any given resource is loaded
only once. There are hooks all over the place, so any BE code developer
must be aware of other extensions that might load resources.

I found minified files in the build directory of extJS.

I didn't check, I only found it in the extensions doc :)
