Well, I think that's not user-friendly. If I open a project I would like
to see that the IDE tells me: install this package and it will work.

Now you are confusing Lazarus with Delphi. In Lazarus it is impossible
to install a design-time package which depends on a run-time package
without installing the run-time package. So also all run-time packages
have to be installed. 

(Note however, that if you use fpmake, you can put the runtime-part in
the fpmake-package, and separately install a designtime-package into
Lazarus. Now in this case I use fpmake, so I can circumvent this
problem. But I'm the only one who uses fpmake this way... 
But then remains the problem: how do I tell Lazarus/the user that he
need to install a package when he opens the project?)

Well, the user will need to know this rule. So when he opens the
project, and the IDE complains that he needs the 'WebDesign' package, he
has to know that he has to install the 'WebDesign-designtime' package,
and not the 'webdesign' package as the IDE tells him to do...
