Source:maxspeed was added to a lot of ways by chriscf, such as http://www.openstreetmap.org/browse/changeset/7529455 and some either side. I don’t know how many other mappers were using it before then, or an easy way to see how many UK ways he added the tag to.
This was based I think on what other countries were doing and had documented in the wiki. Certainly locally I'd already used maxspeed:type and the changeset I mentioned above added source:maxspeed and FIXME:nsl tags. If I were going to have a source:maxspeed I would have said survey. It did lead to some discussion on this list in March and more so in April of 2011, although the discussion seemed to peter out at the end of the week. I suspect everyone had had their say and no consensus was reached. At the time there were 552 uses of maxspeed:type and (globally) 72000 uses of source:maxspeed, so in the last 18 months it seems that maxspeed:type has probably had more usage based on the figures Andy quoted.
