That's why you only use auto_bootstrap=false in cases where you have
already restored the data on the node, or when you are rebuilding a new DC
and know not to ask the new nodes at CL.ONE.

Your asking the wrong nodes for data in the rebuild-a-new-DC case does not
indicate a problem with the auto_bootstrap false + rebuild paradigm.

What makes you think you should be using it in any case other than
rebuild-new-DC or "I restored my node's data with tablesnap"?

As the bug I pasted you indicates, if you want to repair a node before
having it join, use join_ring=false, repair it, and then join.

In what way does this functionality not meet your needs?

I continue to believe you are trying to use auto_bootstrap:false in wrong
cases and that the solution to your problem is to stop doing that.
