Also, this is unfortunate. Any thoughts on how to handle crash keys, which need
to be used inside service code, but registered in a central location near main()
for crash reporting?

Maybe use crash_keys::kActiveURL in chrome code instead?

I would use that key from mus-gpu too, but it brings in more dependencies, so
went with hardcoding the url instead. The crash-key owners were OK with it
(https://codereview.chromium.org/2622073005/#msg4)

//chrome/app/mash is not supposed to depend on any code in //chrome - see
https://cs.chromium.org/chromium/src/chrome/app/mash/DEPS?type=cs&q=chrome/ap...

I'm going to remove the dep and hardcode the string instead, because crash_keys
owners were OK with that for your CL.
