As I have said, I can see both sides - a level playing field (literally) for wheelchair users and others who do not need to use a wheelchair. Alternatively, wheelchair sports are an opportunity for those who don't have a choice about using a wheelchair to have a sporting league that is focussed on their needs.
So, I think value in both? Surely? As long as those living with disabilities have a genuine choice - both are available. Which is not always the case.
And I think spaces that ARE for those living with disabilities shouldn't be a fun photo op for those who do not have disabilities.
