I also agree with these propositions.
Highway=path seems preferable to higway=footway.
For flood hazards, Stephane propositions give the possibililty to take account
of various hazards. The hazard_prone and hazard_type tags should replace the
flood_prone=yes tag that is presently used.

refrain when mapping remotely to use living_street which calls for
on-the-ground knowledge and de facto right of way between vehicle and
pedestrians. This is a tag to better explain/ portray and push to the
mappers down there. More generally, with Jaakko, Brian and Sev we feel a need
to better articulate guide on using highway values below tertiary
in developing countries.

Those usages also apply to a good deal of streets where as a kid, I
learned playing street soccer and hanged out for long hours in wedding/
funerals and later party. I would then stick to Harry's
call: highway=pedestrian and area=yes + drawing roads (highway=residential)
along the edges of the area
