While this is still very fuzzy in current code, this old behavior makes it close to impossible to efficiently use out-of-main temp data, as it implies that we'd need to update refcounts everytime we add something back into BMain (an 'un-refcount' ID usages when removing from BMain). Now that we have two separate flags/tags for those two different things, let's not merge them anymore. Note that this is somewhat on-going process, still needs more checks and cleanup. Related to T88555.
