Doing so is probably not going to achieve much. First we need to defragment OSM itself. It doesn't matter what wonderful tags we come up with here, if carto refuses to render them then they won't get used. It doesn't matter what wonderful tags we come up with here, if editors don't implement them as presets they won't get used. Carto won't (in general) render a tag unless it's widely used. Editors won't (in general) implement tags in presets unless they're widely used. Unless editors and carto support tags, they won't get widely used, so editors and carto won't support them. Chicken and egg. There are complications (of course). Carto (in general) refuses to implement aliases, so whatever the merits of deprecating landuse=grass in favour of landcover=grass, carto will refuse to render landcover=grass. Editors don't (in general) like implementing aliases either. So however much we wish to try to fix bad tags, which are frequently misused because the name or value was a bad choice, it probably won't happen. Some editors occasionally decide they'll ignore the list, the wiki, and carto, and go their own way (sometimes they get their way and sometimes they get a slap on the wrist). So what we need at this stage is not a defragmentation process but joined-up thinking between the various groups. I'm not holding my breath on that one. -- Paul
