I don’t see a problem with it but I prefer to use the baby change myself
I do my changes lying down and baby changes usually have a changing bench and changing pad I can lie down on where as I'd have to lie down on the dirty floor in a disabled toilet.
And just to clarify I don't use the baby changes with plastic fold down tables, I only use baby changes with a solid changing bench like this one pictured
Another option is Changing Places

They have adult sized changing benches and are essentially a more advanced disabled toilet with hoists and stuff, although I personally always find those places depressing so I prefer to stick with the baby change.
