It's too late for that now. If science hadn't labelled Pluto as a planet for 70 years, there'd be no problem. But they did, so now they're stuck with it. And people will keep being annoyed that they've changed it.
The solution is either to change it back, and admit that there isn't a particularly satisfactory "perfect" definition of a planet - or to put up with loads of people complaining until the generations who learnt it was a planet die.
It's a bit like being told that a banana is a berry. That's all very interesting, but nobody but a biologist needs to care. Similarly I believe a coconut isn't a nut.
Or, as the saying goes, knowledge is knowing that a tomato is a fruit - wisdom is not putting one in a fruit salad.
Although saying that, my Nan used to make delicious tomato jam.
