No.  That would multiply the work for the top-level configure 
maintainer and make the top configure script sensive to release 
updates of subordinate packages.  The coupling needs to be reduced as 
much as possible.

Currently top level configure scripts can be quite simple.

I don't mind if configure scripts produce warnings about configure 
options they don't pay attention to.  They should never enforce that 
only options they know about are used.
