I fully agree.

This usage of scripts isn't problematic either as long as those plugins are 
not necessary for making KOffice work. I. e. using python to implement filter 
"superdither" isn't problematic. OTOH, using python to load koffice documents 
is (not that it's going to happen, but you get the point).

Indeed, and I don't oppose custom extensibility by scriptability in any way.

Here, it was the lack of a proper VBA-like script editor with syntax 
highlighting and fully working code completion. Take MS-Office as an example 
on how to do it right. By KDE 4, KDevelop should have the necessary 
infrastructure in place.
