The problem is that every feature implies additional complexity 
and support costs.  Moreover, in case of trailers - certainly 
additional security concerns.

Just adding all possible features won't work, as you will end up 
with a huge and bloated piece of junk.  And that's why I asking 
for real-world use cases to make sure features added are in fact 
needed and benefits from features added outwheigh support costs.

In case of trailers, there is additional argument of trailers 
being [mostly] unused for almost twenty years since introduction 
in HTTP/1.1.
