Those binaries continue to be valid, yes.
I know it's a little late for a wish list, but isn't it in BMC's interest to officially integrate the hotfix?
At some point it will happen and the hotfix is no longer compatible with the latest release and then a new one will have to be built under time pressure. Expensive, error-prone and unacceptable to customers. So why wait, the HF has been finished and tested for 22 months.
