When I get off the road and back to my desk I'll have a look at the "prepared statement" architecture of H2 and decide how that affects the SQL-view perspective. We are also thinking about blowing apart the complex-datastore GroupingFeatureIterator to allow it to map multiple source "back end features" into a well-known target feature. If we can remove the need for sql-datastore and geometryless in this process life will be better.
We really just need confirmation from Gabriel that there are no other agendas - he's not using sql-datastore for any other purposes, and pushed it up out of complex-schemas to allow geometryless to move to a better level of support?

The idea of sql-datastore (ie a DataStore with a SQL shaped hole in the API so you could do joins and mapping) is an experimental idea that has always been on a branch. I have encouraged several developers now (RobA being the most recent) to submit a proposal to GeoTools to make a formal interface for this idea. However with the recent H2 family of datastores being written you are going to have a bit more work cut out for you - there will no longer be a common JDBCDataStore to hack up and you will need to define an interface. So you may want to talk to the developers and make a proposal now while the H2 family is being defined... My impression is that RobA is the maintainer of both sql-datastore and geometryless. You can check the pom.xml file to be sure. My understand is Rob is the only person you need to talk to about bring that work forward.
