Anonymous projects vs anonymous stage rules

Now I can have anonymous project rules:

project
: requirements
<include>D:/Home/libsrc/boost-CVS-HEAD-05-05-21-1305
<library-path>d:/home/lib
<link>static
: build-dir
"../../intermediate"
;

But name for the stage rule is mandatory:

stage x :
projA
projB
: : <location>../output
;

I cannot have just

stage :
projA
projB
: : <location>../output
;

Are there any good reasons for such behaviour, or anonymous stages just 
haven't been implemented yet?
