We need to also test our standalone.xml profile, otherwise we cannot be sure that we have not introduced issues that only appear when using the cut down profile. If we don't do this there is a good chance we will end up shipping a release at some point with a broken default config. 

To be honest I would not be adverse to removing the smoke/basic divide and instead moving everything to web/full as appropriate(or whatever). This would need to be discussed on the dev list though.
