It's just not easy to change these test libraries without fear of breaking tests in random places. I think we have to compartmentalize (as per the latest webrev) to avoid every test with a policy file needing to grant permissions do do container stuff when they aren't container tests.
good point, but I was rather suggesting that tests which use Platform should grant permissions to do "Platform" stuff which, one might argue, should have rights to read any system properties.

improving documentation of "common" test library classes has been in my todo list for a long time, and is definitely an overdue. I'll try to either reprioritize that work or at least compose the wiki-page you suggested.
