This is for the lurkers, in an effort to bring clarity to the table.
Pluto is Pluto. Whatever we call it, it remains as what it is, subject to the slow changes inherent in its character, history , environment and orbit.
Its name is a human appelation that has no significance to its character, history , environment and orbit. It is a convenient label to allow humans to discuss it with ease.
Further, to facilitate deeper discussion, it is classified /labelled in various additional ways (thanks to
@SelfSim for the list). Minor planet, dwarf planet, plutino, Kuiper belt object (KBO), Trans Neptunian Object (TNO). These are artifical categories, with various degrees of specificity. None of them have the slightest impact upon the character, history , environment and orbit of the object we call Pluto.
Attaching an unwarranted significance to how we label it betrays a failure to understand the function of classification systems. Certainly, one may question how appropriate certain labels may be, whether others should be added, or the parent definition modified. But those debates relate to the effectiveness of the classification system and the appropriateness of the labelling for the object known as Pluto.
The musical skills of the The Artist Formerly Known as Prince did not change when he stopped being called Prince. Pluto is still Pluto even if you choose to call it a brotwurst sandwich.
