There's no standard to be "compliant" with. Everyone pretty much
agrees on key-value pairs where the keys are unique. Beyond that, who
knows? I've seen ?a=1&a=2&a=3 and ?a[]=1&a[]=2&a[]=3, for instance.
See, e.g., https://stackoverflow.com/q/24059773/8446.

fwiw, I tend to build my URLs with hackney_url. I don't know what it
does with repeated keys; I've never tried.
