Yeah, that's why I have originally created the LIT_FILTER variable.

Does this variable exist? I've just grepped through LIT source and have not seen it.

I think it should be other way around: "normal" command line invocation should not have any extra flags, then environment variable (e.g. BOT config) modifies that, and then if the test authors no semantics better (e.g. it operates over HUUUUGE inputs) they can override the environment variable with flags.
