you need to think in layers and what you describe is not yet
implemented. So the thing who embeds this lower-level framework in the
Eclipse IDE needs to deal with this.

It might subclass TextEditor or do something different. The important
thing is that the services are 100% the same and language implementators
only need to implement those new APIs and don't worry where their code
is used (Eclipse IDE, e4 RCP, e4 JavaFX, pure Java App, ...)

BTW because this all completely builds upon OSGi-Services (including DS)
it is completely dynamic, so installing support for new languages on the
fly is a no-brainer.
