Is there some reason to forbid dissectors called by the dissector for the
next protocol in the stack to fetch that data?


No. My concern was: if the stack is

IP/TCP/MYPROTO1/MYPROTO2/MYPROTO3

and myproto3 gives back some info, and myproto2 consumes it, maybe myproto1
could check if the upper proto has given something back, and it could get
confused by the fact that it finds something that comes from myproto3
instead of myproto2. But actually, the type should solve the issue.
