Marking as release gating; tool is useful in debugging.

[Ghada Khalil (gkhalil)]

Returning to Frank to re-assign. Irene is no longer contributing to the stx team as her coop term with WR ended.

[Frank Miller (sensfan22)]

As this is a low priority LP and impacts a debug tool, removing the stx.2.0 tag.
