Yes, I explicitly removed this in local.conf:

[gthomas at titan imx6_test]$ tail -n5 conf/local.conf

# Enable local PR server - edit this to use a shared server
PRSERV_HOST = "localhost:0"

DISTRO_FEATURES_remove = "x11 wayland"

[gthomas at titan imx6_test]$ bitbake -e gst-plugins-base | grep ^DISTRO_FEATURES
  ... nothing
