This is all exactly right. I can see a building having any one of about 4 OLC 10 digit "addresses" on average depending on which imagery the building was last aligned to. That is just reality of how we are forever refining our representation of the real world in a digital format. It has imprecision and this is the scale where it becomes really obvious, 13m or less. I am suggesting as a next step, we get a TMS layer that represents this OLC grid and easily displays the 4, 6, 8, or 10 digit long OLC for the grind square depending on scale. Then about 5 of our tools "support" it already because they support TMS layers. I deal with these things at large scale and at the individual door level, we all do who are concerned about this issue, so some tools to help us visualize at scale and quantity these OLC codes will help a lot. Plus the easy to solve case of "looking up" an OLC code is already being added by folks like OSMAnd and OSM if they merge in the existing pull request. I put in issues with two tools that I would like to see support them, the HOT Tasking Manager and Fieldpapers. Having OLC grid layer available in those tools would be very helpful, especially Fieldpapers. A TMS end point would close the one for the Tasking Manager. Searching in OAM by OLC might be nice too, very easy to specify the place and scale with one code. As I said below, lets get these OLC codes that are in OSM now out, if they are even still in there. Vao, myself and whoever else is interested in being able to use OLC to some degree in the eco system of the OSM software community tools will figure out what makes sense and what people want to do and we will go forward from there :) I think TMS layer, whomever, however, or plug in for josm as polyglot said, are all great and would really help the folks who want to work more with OLC to see what, if any use cases it solves.
