Going a bit further, extended status support could be also very useful for other 
entities inside a repository.

A subrepository, for instance, could have a set of flags for its internal state 
(say, "U" for unchanged, "P" for "clean, but at another revision", "W" for 
"working copy changed", "X" for "now my URL points somewhere else"), another for 
its files ("M" for modified files, recursively?), and so on:

$ hg status
A file.txt
M subrepository/modified.txt

$ hg status --extended
A file.txt
W subrepository

(the flags I chose are just an example, of course)

Do you think core support for extended status could be worth including?
