While riding on a bus, I remembered we have an ongoing vandalism in Russia and Israel on the map. Folks fighting it are heroes, and it's great seeing our infrastructure harden. That what wars do, after all.
But, mapping-wise.
(Sorry for the rant)
I spoke about our inability to deal with large scale imports in 2017 ("How to break OSM"). You though it was a joke?
I proposed improvements to API and data model in 2019 to mitigate that. Starting with "area datatype? are you even serious".
Mapping in OSM is and should be strictly volunteer-based. As I wrote to @bdon , OSM is competing with corporations for resources — making it a competition for an outlook on OSM data.
And OSM have consistently been losing the best developers to Mapbox, Grab, Meta, or private endeavours. I have been a sub-par employee at some of my jobs because I wanted to improve OSM as well, and I should not have.
