What is the value in the validation of the URL path as such? It seems
like the client shouldn't really care as to the precise format of the
end user supplied URL as long as the server returns the expected

I'm personally -1 to pinning swiftclient as that will introduce
headaches if someone tries to install ironic along side anything that
expects a newer client or vise-versa.

I agree it seems like a step back, to which I'm curious about the
value of having the check. The forth option is for ironic to abruptly
drop all related code and support for radosgw temp urls, but that too
would be a setback and negative for OpenStack in general.
