This is a good argument with the current set of heuristics.  But with future boolean flags, I think that command-line integration is a lot more convincing.  Two examples: the JVM flags:

and the V8 flags:

If your main concern is the specific interface offered by jsc, another option would be to create another binary.  WDYT?  I think it's useful to have these options in JSC proper, but there is definitely room to disagree.
