Well, it kind of depends whether you think it's easier for five  
programmers to write

if ($speed=~/(\d+)mph/) { $speed=$1*1.6093; }

or for thousands of mappers to learn yet another new tagging rule.  
Given the large amount of parsing that will be required to get any  
OSM data into routeable format, the programming effort in the above  
is trivial.
