Clearly an automated edit: You're replaced highway=yes indiscriminatingly into highway=road without ever checking if the data is even correct. In fact, both this and CS #174269141 didn't even edit any ways but rather guideposts (which follow *=yes pattern to denote the target group), a clear case why automated edits should be taken with care.

This is on top of the fact that these changesets leaves a huge footprint which makes them harder to review: https://wiki.openstreetmap.org/wiki/Changeset#Geographical_size_of_changesets
