Personally?

They're unnecessary.

If done incorrectly, can lead to all sorts of problems.
If done correctly, have to be stitched every inch or so
with vias driving up the cost. Adding guard traces leads
to separating the traces you wish to separate anyway.
Distance is the best cure for crosstalk. Therefore, IMO,
it's sort of redundant to use them.
