But then the question arise : if I create one nice package for a suite 
of components, but user will use only one component from suite in his 
application , does it mean then his project will depend on *ALL* 
components of suite ?

I know that was and issue of adding component registration unit to the 
lpr file uses clause.This was later resolved AFAIK but still information 
about such dependency is bothering me. I have a suite of components , 
some of them in delphi have also additional run-time package. I would 
like to create only one Lazarus package to cover complete suite , 
because of dependency between them. In past there was a nightmare to 
rebuild it in Lazarus ,now it's a lot better (the problem was with 
recompilation of one component and checksum error) but one package 
definitely would solve future problems.
