There are sometimes inconsistencies between actual capabilities and reported 
capabilities, which is a bug then.

But in that case, it is not a bug. the DeleteFeature capability must be 
reported if the layer has an implementation of OGRLayer::DeleteFeature(), 
which the SQlite driver has not. The fact that it the SQLite SQL engine can 
process DELETE statements doesn't influence that fact.

So this is a "feature"
