In subsequent calls, it merges the above file with the version of latex.config in the bundle, giving preference to the com.macromates file. So editing the config file theoretically should not block updates to the bundle's latex.config. But the new environments won't show up in the "Edit Configuration File" command. So I am not sure why it didn't work, your situation seems to be the same as mine. The changes should work without you even having to reload bundles. How did you try them? For me, pressing "oa" followed by ctrl-shift-{, produces an overlayarea environment. Similarly for "op". Is this not the case for you?
