For block development we should only depend on official APIs. But the 
way you start an OSGi server is not standardized in R3. And as we want 
to be able to continue to have the option of having Cocoon packaged as a 
servlet (or at least some of you, I don't care), we need to be able to 
start the OSGi server programatically. Also both Knopflerfish and 
Eclipse has a server configuration file that is used when starting the 
server that differ somewhat, although the concepts are the same and many 
of the properties are standardized.

Yes it should be straight forward. We probably will want to make the 
"OSGi inside a servlet" option plugable WRT to implementation so that 
people can chose.
