We could also create a preprocessor that "unifies" OSM data. For example 
if your target is Mapnik rendering, then would it not be great to have a 
piece of software that merges all these different-values-for-same-thing 
cases, and also drops everything that Mapnik won't use anyway, and gives 
you a debug output for free ("dropped 192 ways tagged 
highway=residentail, reason: not used in map file").

Seeing that Osmosis becomes *the* tool for doing anything with OSM data 
and seeing that it seems to have a workable plugin interface, would that 
not be a good way forward for those who need strict tagging?

This seems to me far superior than trying to meddle with the OSM 
database itself through bots & scripts. The "unifier" could by default 
use a centrally maintained rule set, but if the individual user needs 
something different he can always use a modified version.
