Succeeds #39526.

[rcombs]

This formula fails brew audit --online --strict due to requiring specific revisions of its resources (so setting a head branch for each would be inappropriate); not sure how to resolve that.

[SMillerDev]

You should still set a branch despite the specific revision

[rcombs]

I had to create separate stable do and head do branches to ensure stable builds get the specified revisions. Unfortunately, it looks like I have to have head depend on whatever's in the resources' master branches to satisfy brew audit, rather than using the revisions specified in known_good.json.

[rcombs]

Believe this should all be in a good state to move forward now; anything left I can do?

[rcombs]

I just rebased this without changes, but note that @alebcay had previously approved. Is there anything blocking merge at this point?

[rcombs]

Anything blocking this?
