I am going another way in my own projects. My schedule jobs have the following if.

if: vars.ENABLE_PROMOTE

Well your proposal don't require cplee to add a variable, but it does cost / block at least one action minute for the User

[jsoref]

I've gone both ways in the past. I have no particular preference. My goal is smoothest adoption, and as you note this requires no additional work by the master repo owner.

Since most act forks are going to be public and most forks won't have so many other repositories burning minutes, I think the 1 action minute isn't particularly expensive. That said, I'd be more than happy to use the vars approach if that's acceptable.

the master repo owner

LGTM. I leave this 100% to him, since he is effectively a required reviewer

I also use your approach, but only in cases where the secret is merely desirable and not absolutely necessary for meaningful execution.
