Hi Ian: There are government data, which if they make their way into OSM, is the very definition of an import. Sometimes these data are of such importance, quality or both, the community nods our head and we say, "yes, import these data" and it happens. It is acknowledged that data sources, including these, are a snapshot in time, and do age, requiring updates for our map to be a realistic and accurate-today representation of reality.
There are satellite / aerial imagery, of various vintages, these sources are used to add data to our map database frequently, we might even say "constantly." That is also a methodology the community finds acceptable; imagery layers (and new ones we have the rights to use, and technical instructions on how to enable them in the editor of your choice...) truly abound in OSM. It is acknowledged that data sources, including these, are a snapshot in time, and do age, requiring updates for our map to be a realistic and accurate-today representation of reality. There are "ground-truthed" (verified by humans in the real world) data, completely independent of data published by a government (whether written or electronic) or satellite / aerial imagery. Many (most? all?) consider these data to be a superior form of input into our map. It is acknowledged that data sources, including these, are a snapshot in time, and do age, requiring updates for our map to be a realistic and accurate-today representation of reality. I realize I'm not directly answering your question. I find your spirit and intention to be earnest and good, but I haven't looked at either dataset (existing or to-be-presented-and-entered), so I don't make a judgement about their suitability or quality. So as you ask whether it's "OK to pursue," I hope I've given you feedback which you find valuable to consider about might next be best. You might also consider making a MapRoulette [1] task, which crowdsources the effort across many Contributors, possibly reducing any propensity of yours to "go bonkers." I wish you the best in your efforts to enter high-quality, "fresh" data!
