Hashlink parameterized URL

Regarding parameterized URLs
https://tools.ietf.org/html/draft-sporny-hashlink-04#section-3.2

Can we generalize that for URL segments instead of just query string similar to 
https://tools.ietf.org/html/rfc6920#section-5

Examples:
../hl;zQmWvQxTqbG2Z9HPJgG57jjwR154cKhbtJenbyYTWkjgF3e
../hw.txt#hl;zQmWvQxTqbG2Z9HPJgG57jjwR154cKhbtJenbyYTWkjgF3e

I think there are clear use cases for having it in the path (avoiding conflicts with windows filesystems not allowing "?")
and fragment (doing client side only validation)
