            <p>Ok, I'm impressed...</p>
            <p> </p>
            <p>Can you give some examples of the "tagfiddling" you refer
              to, that annoys you? How do we fix that?</p>
            <p>What tires me, is the lack of any decision-making process
              which is paralysing the whole business, and the lack of
              any (formal) attention for the data quality. Where is the
              (qualified) voice of data architectures, ontologies, data
              modelling, future-proofing, etc etc? All the energy spent
              on these mailing lists debating what are sometimes almost
              trivial issues could better be spent powering a large
              town. Some kind of "poster on the wall", an information
              framework, a metamodel, a data architecture, a governance
              model etc etc might allow some of this energy to be
              directed at more productive things that will enable
              real progress and growth, like 3D, data lifecycle,
              multi-valued and complex-valued attributes, and how
              (process-wise) to clean up and refactor "legacy" tagging
              (to name but a few of the many things that IMHO "need
              attention").</p>

                <br>
                Indeed. It's very possible to "do the right thing" by
                running spatial queries on the data, without a spatial
                database, working directly on a PBF snapshot, and
                running lightning fast in just a few GB of memory and on
                a desktop-class machine.<br>
                <br>
                I can confirm this because I've done exactly that, in a
                tool which I'm delighted to see is proving popular:

                That aside, even if you accept that the interests of the
                data consumer are paramount - which, as a data consumer,
                I don't, and I'm rather tired of tagfiddlers without
                development knowledge second-guessing what developers
                might need - the number of consumers to whom it's
                important to differentiate (say) UK and French no entry
                signs is an 0.001% edge case, not one worthy of defining
                the entire tagging model.<br>
                <br>
                You could just as well argue that you're penalising the
                little guy by preventing him from searching simply for
                "traffic_sign=no_entry" and making him search either for
                193 country-specific values, or run one full-text query.
                Given your concern about doing things "very cheaply",
                I'm pretty sure more people have a spatial index on OSM
