Could you elaborate on why this ought to be an improvement? To me sharing dropsites follows naturally from sharing information.

Yes, the

unlock_shared_dropsites.json
unlock_shared_los.json
unlock_spies.json

technologies are conceptually related, each of them enables a mechanic, rather than changing a value, like most technologies. However, I fail to see the need to enforce a particular order. In my opinion players ought to have the flexibility to pick and choose which ones they want to use, and ignore the others.
Moreover, there is a “Disable Spies” match setting and a mod that enables shared vision from start. Ideally all three ought to be treated similarly: { shared vision , shared dropsites , espionage } × { from game start , with technology , never }, but that's beyond the scope of this patch.

Besides, when playing a “Revealed Map”, you can already see what everyone does, therefore Cartography seems a bit of a waste of time and resources; having to research just to unlock Shared Dropsite is a bit annoying.

It looks good to me.

Good enough to accept?

Convinced on this argument.
