Thanks everyone for your answers!

True, but I would like to expand my profile from line script with
these interpolation methods so using other tools is not really an
option.

Exactly, something like those raster classes but working on individual
points would be great to have in core and in the python API. Do you
think this is a lot of work or is the raster code reusable?

Should I open feature requests for this?
