We are removing process utils from the system, as it’s no longer used to run processes. Unfortunately, there is no “compatible” way we can remove the process utils APIs. This does mean apps that wish to support 7.x and 8.x and use the builder APIs will need to release separate versions for each major line which are compiled against the relevant API versions.
I’m sure that’s not the answer you’re hoping for. My apologies for the hassle. I’ll note that it’s something we’re dealing with internally for our own apps, like the Bitbucket Cloud Migration Assistant.
