Unfortunately there are tens of thousands of plugin writers out there that
are not aware of the dynamics. Eclipse migrated to OSGi 4 years ago and did
some incredible open heart surgery on their runtime engine to support OSGi.
It was quite impressive how they replace their engine with an OSGi based
version while existing plugins kept working. However, none of the existing
code was ready for the consequences of dynamics. Plugins could add entries
to menu's but this information came from a static file in the plugin, so
there was no facility to remove this information. 

Over time, more and more aspects will become dynamic but due to the nature
of massively distributed development it will take some time before the code
is fully dynamic aware. The extension registry is already an example where
the extension points have become dynamic. Now only the apps are left ...

Kind regards,
