note that this can be disrupted for some project in chromium. When I rolled
this, I have to telemetry's page_sets directory to test_page_sets to avoid
naming conflict with the same folder name in content/test/gpu

Can you explain further? Are you saying typ shouldn't do this, or that add to
back would've been better, or something else?

Adding this is good for the reason in https://github.com/dpranke/typ/issues/3.
However, some of the current tests may rely on this behavior & will fail with
this change.

When I roll this change in https://codereview.chromium.org/2072163002/, it
turned out that telemetry has a directory named page_sets which is the same as
content/test/gpu, and that blocked our catapult roll. I had to do a subsequent
fix in https://codereview.chromium.org/2072373002/

I would vote for try to land this, but keep an eye on potential breakages.
