This link seems to assume that a package is always either design, or 
runtime or both?

AFAIK: in delphi you can have the same package as onr runtime, and one 
design time package.

That is you have TMyComponent. Instead of having any "if csDesigning in 
ComponetFlags" you have a designtime package (containing your 
component,with all tghe cdesign code, and maybe prop-editors or the 
like) and you have your runtime package, that has the same component, 
but without csdesign code.

Now yes: the ide only needs to know about the design package, in order 
for you to put the component on your page. => but in this case the IDE 
would add the design time package as package/unit requirements to your 
project. And it should not. It should add the runtime package instead.

Maybe that is something that can be archive with build-modes? While 
compilng the IDE, you use the design-time build mode. While compiling an 
application you use the run-time build-mode. (The packages must have the 
ppu for both build-modes in  it's unit directory).
