This answer is based on the discussion in the comments above.
The updating tag is so ambiguous that we should not make it a synonym of anything; the tag has to be removed altogether. With only 18 threads, the easiest is to manually remove it and let the tag die.
Renaming it into
[bayesian-updating] is another possible alternative, but I do not see that this would be such a useful tag, so I'd suggest we simply eliminate it.
Update: I have eliminated the tag.
