hmm, content/shell is an example of a content embedder. in general, we tend to
allow things by default since we don't do UI.

if this code is used in content_browsertests, can you override the
BrowserContext implementation there? or you can have a setter on this class to
change the default value to false?

(This is not used in any test, unless some tests accidentally visits a website
that ask this permission.)

but, is it ok to give a permission without asking for content shell? I saw that
ShellBrowserContext::RequestMIDISysExPermission() doesn't allow, so I assumed
we're disabling permissions by default for content shell.

[jam, 2014/01/03 00:54:23]

yes, since content shell is just an example of a simple embedder of content, it
should assume the user gives permission for everything.
ah, that's not a good example. let me ping those folks

btw i've sent out a fix in https://codereview.chromium.org/123663002/
