Is it okay to set default X11_TYPE in mk/platform/${OPSYS}.mk as needed?

pkgsrc/mk/x11.version.mk already has:

#       The default X11_TYPE is "native".
...
X11_TYPE?=              native

But some operating systems do not come with a native X11, such as 
DragonFly.

Okay for me to change pkgsrc/mk/x11.version.mk so it says:
#       The default X11_TYPE is "native" unless defined for a
#	specific operating system in mk/platform/${OPSYS}.mk.

And then add:
X11_TYPE?=	xorg
to pkgsrc/mk/platform/DragonFly.mk?

Any other platforms need this also?
