Yes, your description it certainly sounds as if it needs the delay. However,
requiring such a kludge is nothing but a sign of a severly broken proxy/server
and I don't see what libcurl should or even can do to better work with such
software. Do you?

It would be really painful to add the delay unconditonally for all situations
since proper-working proxies/servers don't need this and we'd only slow down
the operation for all those cases then!
