Yes.

I doubt very much whether it makes much difference at all. Its a single
execution per package of a script which takes a comparatively long
time. 

There are multiple places pipelines are used in the script and it would
be fairly invasive to try and use tricks like the ones in the link
above.

If it were something which looped tightly or has a short execution
time, it would make a difference but that isn't the case.

Cheers,
