Now coverage information can be collected if you provide the --coverage to test.py. Internally this uses GCC's gcov instrumentation along with a new script, coverage.py, to parse *.gcov files. The main use for this is finding coverage info during CI runs. There's a risk that the instrumentation may make it more difficult to debug, so I decided to not make coverage collection enabled by default.
