Flashlite: you can't set standard HTTP headers?

It seems you can't set most of the standard http headers in Adobe Flashlite, you can set some custom headers. Ok, it's just like Adobe Flash player security sandbox, but why?
Most of the flashlite applications run in standalone player, not in browser on devices. How I am going to take care of http authentication or similar things. There is no support for more http methods, like head or conditional get requests which make more sense in case of mobile application which run under limited data plan or there is no broadband like stuff for most of users.
I wrote a proof of concept twitter application that runs on flashlite. I want to update it to be like other available apps. I am stuck because Flashlite 3.0 doesn't let you set Authorization header, whereas, Flashlite 2.0 allows that. There are more issues, like you can't set http headers in GET request.
Most of these issues also exist in Adobe Flash player, some are security restrictions which make sense for web applications but don't make sense for mobile applications, as mentioned earlier.
It seems Adobe doesn't get enough feedback in pre-release cycles or doesn't consider for various reasons. Get me on pre-release cycle :-)
Adobe Flashlite rocks, but it has to go a long way, in order to compete with other technologies. It's not always about video, vector drawing, eye candies, standalone games, great visual design, xml parsing or sockets; application development requires more.
