Not really. The previous versions had quite frankestein plugins, in
that they also had an entry point specific for the compositor weston.
Other compositors still needed to handle config in the compositor
itself.
By making all even for all compositors i think the new version is better.

I'm not sre what you mean. Other compositors will not use
weston_config, many needed functions for it are not even exported.
And there is not just weston_config, there also is the command line
options handling which can vary between compositors.
