You need to move the flag to the graveyard, or any Bazel invocation passing that flag will fail. Also, just removing a flag that defaults to false and switching the effective value to true at the same time is a bad idea: Anyone with a setup that doesn't work with the flag set would start getting failures that they can't avoid with a flag any more. So to start with, just flip the default to true.

my thought here was that since this was an undocumented flag for an alpha feature removing it would be ok, especially if that's in the 5.x release not the 4.x release. Also flipping the default wouldn't change much AFAICT since workers can only support 1 protocol at once, so flipping it back to false wouldn't be super useful for folks, still happy to make that change if you think we should, but that's why I just deleted it

It's fair to remove an experimental flag, but I prefer giving users a bit of notice. What bothers me about this flag is exactly that there is no way to negotiate with a worker which protocol to use. If a worker implementation changes from one to the other, there's a real risk of protocol mismatch. But then a global flag doesn't help much, since it would also require other workers to support both. I'm currently doing a refactoring of the graveyards, I'll flip and graveyard this flag afterwards. |

Based on the discussion here bazelbuild#13607 we want to flip this and leave it around temporarily, but there are also some refactorings coming around how to do that. This flips the value now so it can be used without the flag sooner in rolling releases.

Yea workers only being able to support 1 is interesting, but I guess the expectation is users shouldn't need to know which protocol a worker uses anyways? Either way I submitted #13745 just to do the flip now, I opted not to move it around further given your comment about refactoring the graveyard logic |

In retrospect, we should be clearer in the description of this kind of PR. It does not remove the feature enabled by experimental_worker_allow_json_protocol. It just removes the flag and makes the feature permanent. When looking at revision history, it will be easier to understand if phrased that way. |

Now that this feature is flipped I'm less worried about this flag existing and just doing nothing, there's no reason to turn it off. I assumed at this point we might want to give users a bit just so the flag doesn't start erroring since it was so recently flipped. |
|
I'm beginning a quest to remove as many unneeded flags as possible from Bazel over the next year. We just have too many. But, that's just like my opinion. |

I create #14679 |
