It's just _if_ stable really gradually opens up to anything (like code removals, backports of new features, heuristically or AI selected patches, performance patches) it IMO loses its function and we could as well follow mainline, which, I think, is what you are recommending anyway.
When code is removed from stable kernel versions, it is usually for very good reasons, like what happened here. Sorry I can't go into details, but you really wanted this out of your kernel, this was a bugfix :)
I don't remember the details, but look at netdev mailing archives for the discussion. It was something along the lines of the zero day bot found some pre-existing old bug in DECnet, and the consensus was the fixing a corpse was not worth doing.
