it's better to extend ChromeUIThreadExtension function and implement
ExtensionFunction::Run:

https://code.google.com/p/chromium/codesearch#chromium/src/extensions/browser...

see comments.

Done.

please add real UMA for this function.

[rkc, 2014/07/31 23:12:53]

Any particular reason to? We have absolutely no interest in tracking how often
this API is actually used. In fact, we want to get rid of this API pretty much
as soon as we can.

[not at google - send to devlin, 2014/07/31 23:31:17]

the argument that you want to get rid of this API is somewhat compelling, but
there are *no* other uses of the UNKNOWN value. every other private API adds an
UMA. it can't hurt.

Done.
