I want to keep this issue open, as the performance can be increased for such a case.

In the above example, python arr.interp(tension=new_tension, resistance=new_resistance) and python arr.interp(tension=new_tension).interp(resistance=new_resistance) gives the same result (for 'linear' and 'nearest' methods), but the latter runs much faster. This difference looks similar to the difference between our orthogonal indexing and vectorized indexing. We may need orthogonal interpolation path, which would significantly increase the performance in some cases.
