Clouds that were compliant with the interop guidelines before the strict validation patch landed and started failing once it went in could apply for a waiver while they worked on removing or upstreaming the nonstandard stuff. For those not familiar, here’s the patch that created a waiver program:

Thanks Mark for response. I think point 1 is important, it is good to  get the list of clouds or failure due to this this strict validation change.  And accordingly, we can wait on Tempest side to merge those changes for this cycle (but personally I do not want to delay that if everything is fine),  so that we can avoid the immediate failure of interop program.
