But if there was no existing landuse tag what is the harm?
Without visiting each place and doing an on-site survey, how do you know what the actual landuse is?
It worries me that these sort of global search-and-replaces are taking place without any discussion
The best person to decide what something should be tagged as is someone who's been there and had a look. They may be making incorrect assumptions about tag use (think of the various odd "designations" that pop up from newbies that are really "descriptions"), but in that case the best way is to discuss it with the mapper concerned, then raise on a list such as this one if they insist on "doing it wrong". In most cases with non-newbie mappers there's usually a genuine reason why they've tagged things as they have. Any attempt to restrict tag use like this will restrict the usefulness of the data, in this case to "well it looks green on aerial imagery", which anyone in their armchair can see. The advantage of OSM over other maps (even over the OS for most of the country) is having people who actually go there and have a look, not just take as given what e.g. a local authority thinks is there, or what it looks like from a few thousand feet up.
