Absolutely. The lack of anything secure to lock to seems odd to my BRITISH sensibilities, and ideally one or more of the spaces should be wide enough for tricycles, but I've seen how big dutch cycle parking facilities can be, and it makes perfect sense to provide dedicated parking near the whatever for the walking-impaired cyclists.
I think a blue badge scheme has some merit, in the absence of general recognition of cycles as mobility aids. (Which would be preferable, because many people don't want to think of themselves as disabled. See the Dutch phenomenon of people wheeling bikes around that they haven't been able to ride for years because that doesn't come with the same loss of dignity as using traditional mobility aids.)
UK law is interesting, in that the definition of a manual wheelchair (Class 1 Invalid Carriage) would include any non-motorised[1] cycle that has been designed or adapted for use by a disabled person. Which means that a disabled person should be within their rights to cycle on the pavement etc. as long as their cycle has a crutch holder / adapted pedals / modified brake levers / whatever. I don't think there's any case law, thobut.
[1] As soon as you put a motor on it, it either has to be a Class 2 or 3 Invalid Carriage (mobility scooter) or a Pedelec (e-bike), else it's a motor vehicle by default.
