Build dirs and in-path features

While reading some previous posts related to build dirs I thought I chip in.

I think scons is more intuitive regarding this issue. By default it 
builds to the same dir *but* it also computes hash of all commands used 
to build a certain file. If the user desires a different build dir can 
be specified (a variant can be created).

This has several nice properties. The most important (at least for me) 
is that if you change the SConscript (Jamfile) the relevant files are 
rebuilt. This very thing hits me again and again. Combined with the fact 
that "--clean" or "-a" options behave strange (clean too much/deep), it 
is very hard to use. Also the build hierarchy of scons is more intuitive 
and the built files can be more easily found. [if only scons had 
user-requirements I'd really consider switching...]

What is your view of this? Do you think that the complicated build dir 
structure has some important properties that I do not see? Is it 
superior in some way?
