I think you're making a false equivalence here.  One can see argument
ordering consistency as a serious problem without seeing a Heath
Robinson version of call chaining as the solution to it.

I appreciate that you want to seize onto any opportunity to fix the
argument ordering consistency problem, but I don't agree that this is
the fix for it.

If it were so natural, wouldn't the original version of these
functions have been made "right" in the first place?  I fear that the
only thing we'd gain by adding all these aliases is more functions,
but without the benefit of any improvement in the argument ordering
problem because now, instead of remembering which order the argument
is in, users have to remember which alias to call.
