[pdal] filters.smrf question

I'm fairly new to pdal but i'm trying to write a pipeline to utilize the
filters.smrf in order to classify ground as well as keep unclassified
points or better yet keep the points not reclassified in their original
classifications. The pipeline i found creates a beautifully dense ground
surface but there must be a way to keep other classifications that weren't
determined to be ground right? The majority of the points i'm trying to
"search" to determine if they are ground are in the unclassified class (7)
so i can't use the ignore function right?
the pipeline is used is:
* {*
* "pipeline":[*
* "528000_5392000_1000.las",*
* {*
* "type":"filters.smrf"*
* },*
* {*
* "type":"filters.range",*
* "limits":"Classification[2:2]"*
* },*
* "output.las"*
* ]*
*}*
Any help would be greatly appreciated.
Thanks,
