Are you saying you want to ensure that the navigation is safe for vulnerable road users?

The walking distance for this trip is 224 metres (your change hasn't taken effect in routing terms yet) https://www.openstreetmap.org/directions?engine=fossgis_osrm_foot&route=53.27359%2C-6.35571%3B53.27375%2C-6.35324#map=19/53.27371/-6.35417

Once your change takes effect, the walking distance will increase by about 100 metres. This doesn't reflect the reality of what route a pedestrian would actually take to reach that destination from that origin.

Here is another example.
870 metres walking distance.

Same origin and destination as above, but in google maps: 450 metres walking distance.

I would ask that when deleting the footpath connection that existed at the end of a cul-de-sac and creating a separate highway=footway alongside a highway=* road, you ensure that connections are added at junctions with other roads so that pedestrian navigation is not compromised like this.
