I assume you're talking about sid or jessie. For wheezy you may want to try the backport of v204.
There may be some misconceptions in play here: as can be seen from the udev rules here (for v208 currently in sid), the udev developers explicitly chose the kernel cmdline as the default way of enabling this functionality.
I don't see anything inherently "overkill" with using the chosen interface for it and simply putting
/etc/default/grub. Is there any specific side-effect you're worried about?
The fact that the answer you mentioned suggests removing a file to disable it is a hack (at least in Debian's case) that wouldn't work in the long-term because in debian those rules are stored in
/lib/udev/rules.d, i.e.: they would get overwritten in an upgrade (besides, disabling functionality by effectively removing the file that describes it makes some sense, but enabling it is fundamentally different, so I think this is an unfair comparison).
OTOH, if you have a concrete reason for not using the kernel cmdline, you could report a bug against the debian package and have the maintainer move these rules to
/etc/udev/. Then you could theoretically switch between the current "persistent" and the new "predictable" rules.
But just FYI: looking at the sources for version 209, it seems to get rid of the
net.if_names check altogether, so your question may need some readdressing in the near future.
