Is there a way to create a vectorized gaussian blur?

[SHIIFT]

I usually work with different sizes on the same document and I was wondering if there is a vectorized version of gaussian blur (or something that has the same function) in order to resize it without expanding the object. Also I have to say that I do not like this effect that much so I would like if anyone can tell me another method to create something simillar to it.

Try a blend.

gaussian blur is pixel based that is also why it is difficult to manage.

Try using feather this can be scaled better.

Feather is also a pixel based raster effect and does not scale better.

Blends, gradients  and meshes can simulate a scalable blur.
