You could achieve that now by creating a dummy variable, and instead of
using a new handler for the rewrite by code, you wrap the code around
the setby lua code. It would waste a few cycles, since it would be
setting a variable unnecessarily, but would have the benefit of not
slowing down the execution of code that didn't use rewrite_by, since it
wouldn't be adding an extra handler to process for all the other requests.

A better way would be to extend the NDK and expose a generic
rewrite-phase, script engine interface that other scripting functions
(that are more than just set_xxx) can use, and to use that instead.
You'd then not be wasting cycles on setting a variable unnecessarily.
It'd be mostly similar to the set_var stuff, but would need to take the
normal 'code'-type functions rather than the NDK setvar function types.

Cheers,

Marcus.
