Developing share pod using Flex 4.1

Question:

What are the possible bad consequences of developing an Adobe Connect share pod using Flex SDK 4.1?

To elaborate:

I am developing a share pod using the Collaboration SDK. The documentation for the Collaboration SDK states:

Collaboration Builder applications must use the Flex 3.5 SDK and be compiled for Flash Player 9.

For the pod I'm developing, I want to include features (namely OSMF 1.5) that require Flex SDK 4.1. The thread on that is at: http://forums.adobe.com/message/5992344.

The share pod (developed using Flex SDK 4.1) so far seems to work, including sending messages through the Syncconnector. But I haven't tested extensively and I'm worried about encountering issues as I continue down this path.
