Woohoo! I've been contemplating making such changes for a while. For the 
sames reasons too :-) But...

That one broke my builds :-( For the longest time I've had these lines 
one my root jam files:

   type.set-generated-target-suffix EXE : <target-os>linux : app ;
   type.set-generated-target-suffix EXE : <target-os>windows : exe ;

I know the windows one is redundant. But I hate assuming, and hence 
relying, on default settings like this. And the "app" one just personal 
preference. Now I get this error:

C:/DevRoots/RSI/work/projects/facets/product/sdk/boost-mini/tools/build/v2/build\property.jam:613: 
in find-replace from module object(property-map)@1
error: Ambiguous key

Which I verified is from the extra windows target suffix by commenting 
it out. It doesn't affect me terribly... But this error also means one 
can't override the default suffix. I.e. one can't do:

   type.set-generated-target-suffix EXE : <target-os>windows : run ;

It seems like a bad idea to remove the ability to override defaults.

Hm, the cross-compile on MacOS for iPhone has the same "long command" 
problem. I end up running, with an alias:

   bjam toolset=darwin architecture=arm target-os=iphone 
macosx-version=iphone-2.0

How are you thinking of reducing things like that?
