Most consumer mesh systems do not support those 5ghz channels that mandate DFS. I can’t think of one that does support them, although numerous non-mesh systems do support them. If your router(s) do support those channels, they can be quite nice to have in a residential setting, as people I’ve observed tend to not have equipment operating in those channels. High traffic airports can be a problem, as you and the article mention, since DFS may get triggered with great frequency. Nearby military bases in general (not just airfields) may also result in burdensome DFS triggering, although YMMV.
