Actually I think we do need a different tagging and also some different interpretation of the maxspeed tag itself: * First of all the maxspeed key should always contain the maximum allowed speed - even if it may vary. And it should always be a number. The only exception should be "no" for the cases where there is no legal speed limit. So IMO "signals" should be deprecated (currently used about 4000 times -> 0.18%) * A different tag should be used if the speed limit is somehow managed, maybe maxspeed:managed=yes or something similar. Why do I think that maxspeed=signals is a bad idea? Because it doesn't carry a lot of useful information. The speed limit is especially important to routing applications. For such an application maxspeed=signals is no information at all and it might fall back to the country-specific default limit - and this may (and will quite often) be wrong.
