(for various reasons I needed to join a mismatched pair of 18v drill and battery, annoyed at how much fun it was)

I thought there was communication between the drill and battery that would keep this from working.
Some brands have the BMS in the tool, others have the BMS in the battery. When it's the latter it's fine to mix and match.
Is there data as to which producers use what method?

Thnx
Google I guess 🤷
On higher end ones maybe, but this works fine so idk - it's conceivable they both use the same internals just with a different battery mounting geometry
Mostly only the charger cares. A tool often only has power contacts. Something "smarter" like a camera with battery life gauges in the menu etc will most likely want to talk to the battery.
But if the company thinks the extra cost in manufacture is worth it, they'll probably choose evil.
