On the whole I don't see any real difference between the two except Shift Paths will do both Negative and Positive with differing results.

With a path structure like {A;B;C}

Trim Tree will go {A;B} and {A} with the inputs 1 and 2

But Shift Paths will do the Same with -1 and -2 but it will also shift the other way with positive inputs e.g.

{B;C} and {C} with 1 and 2 but the important difference here is that the paths are not combined.

Edit: Why you would want this I haven't worked out yet. Maybe a partial Simplify

Double Edit:

Yes definitely useful collapsing from the front of a tree

Looks like you left out the negative that makes shift paths work.  With that change, there once again seems to be no difference between the two.
