the text above would suggest so ...
is there a problem with this?
does it not match something which was agreed upon? (no i dunno)

the possibility to write info packets anywere was removed in
r16507
at that time we still had info streams, which where later droped


also for the case of realtime streams where song info is updated at the
song start, well there must be a main header there anyway or you cant
start listening ...
the exception would be if the main header is transmitted out of band with
SDP or similar but then the info packets could as well be transmitted
out of band instead of blindly sending them duplicated a few times ...
