The new version of the draft contains the changes based on the list comments from Paul and Roman.
As far as I can tell, the misaligned issue has now been fixed as far as BUNDLE is concerned, so unless someone is aware of something else that needs to be fixed I think we can initiate WGLC. I see no reason to hold it up.

This specification defines a new Session Description Protocol (SDP)
Grouping Framework extension called 'BUNDLE'. The extension can be
used with the SDP offer/answer mechanism to negotiate the usage of a
single transport (5-tuple) for sending and receiving media described
by multiple SDP media descriptions ("m=" sections). Such transport
is referred to as a BUNDLE transport, and the media is referred to as
bundled media. The "m=" sections that use the BUNDLE transport form
a BUNDLE group.
This specification defines a new RTP Control Protocol (RTCP) Source
