Not sure what the behavior is if command_line_switch == "". Is "" the same as
wildcard?

Correct. That function is private now but I'll update the comment.

I don't think we need the profile_directory for this - background mode is
defined as loading *all* profiles at startup that have a background app
installed, via ProfileManager::AutoLoadProfiles().

Likewise, this shouldn't need to take a path (see my previous comment on
EnableBackgroundModeAtLogin()).
