This changeset appears to have deleted large amounts of information from the map, and also made some clearly-incorrect changes such as changing an airport runway from being tagged correctly to being tagged as a building and a residential road.

I believe it should be reverted, but if you think otherwise, I'd like to hear why.

(I'd note that I haven't reviewed any of the other changes, but given the amount of construction in the area, likely some others are suspicious as well.)

I reverted one of these added ways in osm.org/changeset/58274867 because it was based on very out-of-date imagery, and the parking lot has been replaced by a building site with a building under construction. (This should perhaps have been obvious based on the landuse=construction at that location, and the history thereof.)

This road was demolished over a year ago and has been deleted multiple times already, most recently in osm.org/changeset/40218345 . Please be more careful when using out-of-date imagery, particularly when the area is *marked as landuse=construction*.

This changeset added a ton of parking aisles that used to exist but no longer do, due to construction. Please be more careful when adding things in areas marked as under construction based on old imagery.

This was the same incorrect edit made a few weeks earlier in osm.org/changeset/49505749

FYI, this changeset added a bunch of details to a parking lot (based on Bing imagery, I presume) that was replaced months ago by the construction of 160 folsom (and which I then removed). It's perhaps worth being a little more careful about adding things based on imagery for things mapped as construction sites that are likely to have changed recently.

This changeset readded a ramp that was demolished last year (and which had been removed from OSM after its demolition) -- the bay bridge offramp branching to the corner of Fremont and Folsom, way 397267324. I've removed it again, since it no longer exists.
