In OSM there has always been "space" to add new detail. What one person
finds a ridiculous level of micro-mapping, someone else may consider
valuable data. For example, I as a cyclist am not bothered about
maxheight=* but truck drivers are. In the past there has been no clear
process evident for deciding where to draw the line. If someone wants to
create a navigation model for learner drivers, then why not? Who are we
to say "that doesn't belong in OSM"? Where are the rules for that? Our
job as a community is to guide the development of the tagging so that it
is fit for purpose (now and looking into the future) and compatible with
what is already there.
