What is the point of this passive-aggressive comment, please?

The way had the following tags: access=no + bicycle=yes + foot=yes + highway=path.

This is an awkward pile of access tags, and it was subsequently changed to remove access=no, which has adverse effects, among others, on rendering.

The changeset did not change access conditions for pedestrians, cyclists or horse riders.  In version 2, horses were disallowed (because of access=no); in version 3, they are still disallowed (because of horse=no), so why would this be a problem?

In case you are not familiar with how access rules are cascaded, this page might be an interesting one to read.

Have a nice day.
