A better approach if possible might be to default to -1, or something else indicating the absence of data, but otherwise I completely agree with this. As posted on wikidata-l, taking the current approach of +- 1 SF is a really bad idea. As an example, say you have a length of 100m. Which significant digit do you assume is correct? Is this +- 100m, 10m or 1m? What if it's referring to the length of a 100m run, where the accuracy could be much higher than the significant digit given, e.g. 100m +- 1cm? Or what if it's the size of a crater on a distant planet, where it might be 100m+-50m? Or if the actual value is 100m +- 3m, but we say that it's +- 1m (which I see is the default in this case), which might be believable to readers but very misleading in reality? If there's no uncertainty given, then please just say that rather than trying to make one up!
