no need to create a separate component (i.e. .so/.dll in component build) for
subdirectories in content.

If you just want to make sure it doesn't grow dependencies, you can make this
directory's DEPS file exclude content. then just add it to
private_browser_sources in
https://cs.chromium.org/chromium/src/content/content_browser.gypi?rcl=0&l=353
which would also fix the gyp broken

sorry I know Brett mentioned otherwise in his email that you can use BUILD files
(along with DEPS) to limit the dependencies.  We're not yet at the point where
we have different source sets for small directories in content/ (or other top
level directories other than components) until gyp is removed. tight DEPS rules
will accomplish almost the same thing though.
