Maya doesn't have a native smooth deformer?

I could be wrong on this one but I couldn’t find any menu entry for a smooth deformer.
A google search gives me only third party smooth deformer.

Am I missing something or maya doesn’t really have a native smooth deformer?

P.S. I don’t count subdivide command as a smoothing deformer. Smooth Deformer (like what is in other DCC) performs a relax operation between vertices so they are evenly distributed. And they don’t increase the vert count.

I know right?
You can get to one, though. Do a DeltaMush, and set the “displacement” attribute to 0

Ah gotcha!
Displacement to 0. That’s the missing link.

I used the Delta Mush but it only works on animated object.
So the displacement to 0 makes it so that it is also possible on static object.

Thanks!

For what its worth: Here is a little code snippet that does vertex smoothing:

'''
Simple PyMel smooth (NOT subdivide) algorithm

A simple example of a smooth algorithm in PyMel. This is NOT fast or optimized!
The math behind it is as follows: 
 - The new position of a vertex is the average of its position and all positions of its connected vertices.
 - The weight of original position of the vertex is the same as the number of connected vertices.
