Thanks for this piece of history and survey, Martin.
But my point is not liking but just being logical.
I find it very strange to say: use source:maxspeed
<http://wiki.openstreetmap.org/wiki/Key:source:maxspeed>=* for type, but
if you need to use source as source, use maxspeed:type
<http://wiki.openstreetmap.org/wiki/Key:maxspeed:type>=*.  Especially if
you deal with someone else's tags and you must transfer their
source:maxspeed
<http://wiki.openstreetmap.org/wiki/Key:source:maxspeed>=* to
maxspeed:type <http://wiki.openstreetmap.org/wiki/Key:maxspeed:type>=*.
before adding your own source:maxspeed
<http://wiki.openstreetmap.org/wiki/Key:source:maxspeed>=* !!!
And, further more, that this explanation is mentioned only for source=*
and not for maxspeed=*, and that national instructions and presets
reflect only the latter, totally missing the point and aggravating the
situation.
Is it too simple to simply use maxspeed:type
<http://wiki.openstreetmap.org/wiki/Key:maxspeed:type>=*?
Yes, I know, I'm not fuzzy enough ;-)

I have just mapped a bus line. While doing it, I made dozens of
corrections because, pardon me, OSM needs them badly (access=yes,
bicycle=yes, foot=yes, motor-vehicle=yes, repeated JOSM congratulations
etc.).
Who does seriously think that a mapper will purge his bus changes in
order to make other changes without mixing sources? I even had
compelling reasons to make a global update (saving to OSM local file).
The changeset source idea comes from bulk importers for which it's
all-right.

Best is to use OSM consequently, each our own way, as our reputation.
