Yes it does. There's no logical reason to think it doesn't.
You do have to set some kernel options, but that is true for just about
everything in the kernel - you won't have support for hardware X unless
you enable hardware X in the kernel config :-)
One of the additions with gentoo-sources is the very first menu item,
all it does is enable a bunch of stuff that supported init systems
(openrc and systemd) use - it's purely a convenience measure and doesn't
change the kernel itself per se. systemd for example will need cgroups
enabled, openrc needs udev-mount. It's all in the ebuild, and portage
throws an error is something required is not set in .config.
