Eh. As a non-earth-centered pagan, I'll complain less about moon cycles than some other things--depending upon exactly how it's put. Although my path doesn't emphasize or align with nature, the phase of the moon does come into it *somewhat*. Not in the sense of having some magical or spiritual significance in and of itself, but because the first sighting of the new crescent marks the beginning of the month on my religious calendar. If someone expects me to find some sort of Big Cosmic Significance in it, yeah, I won't be doing that on a religious level. But moon cycles being significant? Well... Yeah, sort of, kind of.
Even that won't be universal, obviously, but "moon cycles" does cover a lot more ground than "earth-based".
You're right. Also, I phrased my point pretty badly, and I'm sorry for that. What I mean is that there's such a varying degree of significance that I personally would have a hard time agreeing with it being described as universal.
