I might not have picked the best example, but the current keywords make it 
simple for me ;) 
Let me rephrase then , it is not self-evident which keywords are ATM-specific 
then… But humor me:
tc qdisc add cake help
Usage: ... cake [ bandwidth RATE | unlimited* | autorate_ingress ]
                [ rtt TIME | datacentre | lan | metro | regional | internet* | 
oceanic | satellite | interplanetary ]
                [ besteffort | precedence | diffserv8 | diffserv4* ]
                [ flowblind | srchost | dsthost | hosts | flows* | dual-srchost 
| dual-dsthost | triple-isolate ]
                [ atm | noatm* ] [ overhead N | conservative | raw* ]
                [ wash | nowash* ]
                [ memlimit LIMIT ]
    (* marks defaults)

Where is it evident that “conservative” includes atm encapsulation? And what 
should a user expect that specifies “noatm conservative”?

        So Jonathan, please, instead of trying to argue obvious inconsistencies 
in the currently assigned encapsulation keywords away, just go and make sure 
they are consistent and well documented. 
        Your postings in the overhead-matter make me question whether you do 
fully understand the issue at hand in its full complexity; so by all means go 
and collect input from users (usability and self-evidence of the keywords) and 
experts (on the actual likelihood of encapsulations).

Best Regards
        Sebastian
