I rather don't explicitly care whether it is, or isn't. I just want a decision not made by 'the public'. (The moronic kind; that legislate that it's a planet, or that PI=3 (really)) Because they can't (consistently) have Pluto and not Eris. And Quaoar. And several others they won't be able to pronounce with any more credulity, than when they ask to see pictures of Uranus.
This was, more or less the reason for the (contrived) definition that IAU got, and in fact I think it's fine; that it means 'planet' tells you something about the /solar system/ because of the implied orbital dynamics (Kuiper Belt - is not the same region as where a few trojans are hanging around - neptune shaped it). Not just that it's a ball of whatever (or literally, just a ball). Whether or not that definition makes sense for any other solar system (and IAU already said it doesn't), being something else entirely.
Pluto is clearly a world more fascinating than we could have hoped for (and Triton set a few expectations has Pluto roundly beat). And there's more than just it out there, that is even within our reach.
I don't think the classification degrades it (many seem to). I think it's solveable, as a matter of emphasis.
'The public' let's be realistic after all has no appreciation of what these bodies are, or if they do, it's as those nice pictures that are all more or less the uniformly biggest sphere that could fit on the page, or from bad (or less bad) TV sci fi shot in studios at 1G.
But (as I'm sure many here actually know) ref: http://scienceblogs.com/startswithabang/files/2013/11/Solid-Solar-System-Planets-Compared.png - they are - severely - not the same size. At all.
What is _your_ minimum cut off going to be? Every grain of dust?
There are arguably only two 'major' terrestrial planets in the solar system, based on what it'd mean to us to try to run on it (rather than hop) without faceplanting. I'm not saying that's what I'd pick. But in PR terms there'd then be 7 rocky planets - two major ones. and 4 giants (2 gas, 2 ice) and you can call that 11 if you want, and a lot of dwarves.
Sooner or later each press place with only humanities grads trying to figure it out will use a different number, and people (americans) will stop caring. While highlighting at the same time, that the amazing thing, is that these bodies are *nothing* alike and thus worthy of a lot more space flybys and orbiters.
Most (all?) other astronomical classifications get away with not changing, and noone cares (see supernovae, star spectral class, etc). But WIMPS still can get on with finding their MACHOS regardless.
