E.g. we add explicit maxspeed tags to roads inside settlements where the maxspeed is implicit (within the city limit signs), and add source:maxspeed tags (e.g. value IT:urban in this case) for the unlikely case, that the law changes, so we can automatically select all ways with this referrer and change their maxspeed in one go, without needing to care for signedposted maxspeeds with the same value (because they should have source:maxspeed=sign or maybe nothing). At least this is the theory, so far we haven't needed it. Even if your regulations are not national or by the state but only in your county or township, you could add some additional tag that refers to the ordinance, so if it changes you can change all those cases in one go.
