I was explaining this to a friend recently and I think it's an important distinction to make: not all queerplatonic relationships look the same.
A good way I've found to illustrate what exactly a qpr is, is to say "a qpr is to relationships what nonbinary is to gender". While both of these traditionally function on a binary (male/female, platonic/romantic), by defining our personal outlooks and experiences of the concepts of gender and relationships with new terms, we challenge the boundaries that society has put in place.
And yes, whilst redefining what actually constitutes romantic or platonic relationships, or male and female identities, and what makes them different (and acknowledging where they overlap, or where they can expand past what we traditionally expect) is important to increasing our understanding, so is providing options entirely outside of those two boxes.
And that's what it is - options. It's very easy to trivialise the concept of nonbinary and simply make gender into a trinary, rather than a binary. Male/female/nonbinary, which goes against the very purpose of the nonbinary label. This further erases the spectrum of gender. It's the same with relationships - by giving a strict set of instructions on how a qpr must look and act, you are simply creating a trinary. The point of the concept of qprs is to acknowledge that there are relationships between people that may overlap platonic and romantic, or fall partially within one and partially outside, or ones that are entirely separate from either category.
There are an infinite amount of ways a relationship can manifest, and if the people in the relationship feel that queerplatonic best describes their partnership without romance, or their affection without commitment, or their feelings towards each other that aren't quite what romantic or platonic is to them, or any other reason that rebels against amatonormativity, then they can choose to use that term. Queerplatonic covers the widest range of relationships that come in all shapes and sizes.
I think it's so important when discussing topics like relationships and gender to consciously make the effort to keep queering our ideas of the concepts - to remember that a spectrum is a spectrum. Labels can be useful for finding community, identifying your experiences and validating your struggles, but as soon as you try to start hyper-defining them, you lose the radical nature of queering our understanding of ourselves and our relationships. We name these concepts in order to give a voice to our subversion of society's arbitrary rules and expectations, not to police each other into conforming to a particular understanding of how a person (with a certain label) "should" act or be.
