I think that developers have to announce it.

 (from the manual):
* r.surf.idw:
... attempts to minimize the number of input data
 ... r.surf.idw will generally outperform r.surf.idw2 except when ...
* r.surf.idw2:
 ... does not work with latitude/longitude data bases.

Question: why do we have to keep r.surf.idw2?
