well i guess i have to take the blame for it ... 

the motivation i had when initially debugging networking problems
using tcpdump was that some decoders do generate a lot amount of
information, some others don't and again others display just
default parameters - [bootp/dhcp is a good example here];
it was the inconsistency and the non-completeness of the
per-protcol decoders that triggered my interest;

so during the course of last year i have re-worked most 
decoders (ospf,is-is,bgp,ldp,rsvp,bootp,cdp,chdlc,ppp)
to be very quiet. just print basic information and
omit everything else behind the -v flags, which may by far
not be perfect but now its at least consistent ;-)

i admit that for the bootp/dhcp decoder i could have at least
left some more information [typically the first layer of
the decoded protcol makes sense e.g. IS-IS PDU type,
OSPF packet type etc ...]
