Granted that the name "funky" is inherited, I think that in an odd way it does have purchase.
With the benefit of hindsight it's clear that a big part of the appeal of more conventional funky house was, perhaps from the beginning (or certainly from 2005), a certain allegiance to syncopation, the push-'n'-pull between the 4X4 kick and the counter-rhythm patterns on top, which perseveres in current funky.
Hence the Dennis Ferrer mix of "The Cure and the Cause" being such a pivotal track in the UK scene's emergence as a distinct (though not necessarily original or innovative at that stage) scene in itself.
While soca patterns have a huge role within current funky, it's also clear that they don't exhaust the current rhythmic template of the genre (no-one in this thread is saying it does - I just want to be clear). In this sense that soca beat could be said to occupy the same role as the basic 2-step beat in garage - lots of tracks use it or a variation of it, but it's only the most obvious of many forms the rhythmic template thows up.
However, I think you could characterise the overall rhythmic template as being one in which counter-rhythms are given a more decisive and prominent role, at times resulting in the abolition of the 4X4 kick (e.g. "A Little Bit Funky" or "Always Be Mine" - though even on tunes like these the absent kick has an implied presence in a way it didn't in, say, 2-step).
Off the top of my head I can't think of many tunes at all which just use a straight house beat with no counter-rhythmic adornment. That awsome Spryo tune on Marcus Nasty's November set with all the MCs toasting on top comes to mind, but even there there was a counter-rhythmic 5-pulse-per-bar chord which provided the same push'n'pull tension. You don't get really monolithic 1-2-3-4 tracks that predominate in regular house.
It's that sense in which "funky" actually means something still I think - whether it accords with more conservative definitions of funk is a separate question, but I'd say if it did the music probably wouldn't be as interesting...
