Yes, my English is not the best. Sorry.

You misunderstand. My gambas3-gb-runtime package doesn't contain the
gb.gui and gb.gui.opengl components. If I create a Gambas application
without GUI, not load unnecessary components. But gb.gui component is
depend from gb.gtk and gb.qt4.
And if I follow the spec, then I have the opportunity to create a
gambas application that works on my KDE desktop, but did not work on
GNOME. Because IDE is use the gb.qt4 component, my app is use gb.gui,
but gb.gtk doesn't installed.

No, I'm not forcing anyone!

You misunderstand. The IDE not work without gb.form.stock component. So
if I follow the spec, do not start the gambas3.gambas.

If I create a Gambas application with gb.desktop component on KDE, and
if I package it, this app maybe doesn't work on GNOME. Are you sure
that is how it should work?
I understand, the lib is use some RAM, but it's dependency. The
gb.desktop component maybe not work without gb.desktop.gnome on other
desktop.

Yeah, this right and I follow it if possible.
