You appear to have tagged sections of the High Street/Steyne Road roundabout as foot=no in response to a StreetComplete task asking "Are pedestrians forbidden to walk on this road here?"

I have checked the available Bing Streetside and/or Mapillary imagery for evidence that there really is a (signed) pedestrian prohibition here. I cannot see any TSRGD diagram 625.1 "pedestrians prohibited" signs on the imagery, so do not believe that a prohibition exists and have therefore reverted your edit.

The wiki states that access tags reflect legal access. Subjective opinions about whether it would be pleasant, a good idea, safe, etc. for a particular transport mode are not relevant to legal access.

As real pedestrian prohibitions on public roads other than those tagged as highway=motorway or motorroad=yes in the UK are quite rare and are always signed, this quest is probably better left disabled. It is disabled in the UK from StreetComplete v59.0 onwards.
