Comment 3 for bug 2017023

I agree with Sean, as long as we have the APIs (nova proxy APIs) even they are deprecated but keep/should work for older microversion, having tempest test is good coverage for them and we should not remove them. Once those APIs are removed then we can think of removing the tests. But than also Tempest need to test them until they are gone from all supported branch by Tempest master. And removing those APIs from Nova is another complex thing as increasing he min microversion is not easy thing.
