De facto doesn't make anything a standard, a proposal does. 
De facto, millions of road segments have tiger tags from old imports. That doesn't make keeping them a standard in any fashion. 
De facto, large areas of the US are missing building footprints. That doesn't make "no buildings" a standard.
De facto massive amounts of major roads have lane tags not matching the ground truth along the entirety of the segment, because someone looked at a subsection of that way at some point only when they tagged the entire segment. Again, that doesn't make having miles and miles of road tagged as two-lane the standard when in reality there's sections turn lanes along that segment.

If you want to enforce your preferred tagging style as the standard, there is a process for that - a proposal. Until then, please respect that your preferred style is not everybody else's preferred style. 

Also, be careful with just blindly "inferring" that every way in a route relation should have the segments tagged and forcing these tags in without any further verification. This probably fits the definition of a mechanical edit (which I'm assuming was not discussed in the proper channels either?)
