Some(/many?/most?) downstreams maintain their own copies of older code and data and cherry pick updates to maintain maximal backward compatibility to avoid breaking their customers production systems, generating bug reports, that costs them effort, time, and money to deal with.
Yes, when we removed the SystemV/* names a couple of decades ago, some suppliers kept them around for awhile for compatibility reasons. I doubt whether that'd be useful for the current change, though, as it's a smaller change from the user viewpoint.
If we keep the rules for regions common, but have similar zones for different political entities at similar longitudes, we can maintain a balance, and still reduce effort.
I'm not so much worried by the technical effort of maintaining Sweden data separately now, as by the political effort of justifying why we treat Sweden differently from Kosovo or any number of similar candidates in the future. Saying "we've always done it that way" is not sufficient justification for a political decision.
