Note that I did not imply that restoring the service to a different project or provider would always be easy or fast (certainly in the case of very large data volumes it would be neither of those things). I was addressing the prospect of losing "years of work" as was stated in the OP. That sort of implies that most or all of what they did over that time is recorded only in the current state of the GCP project that was disabled, and that is a really terrifying position to be in.
