Definitely trickier than before, but still works with few adjustments. Assuming nothing changed in the last week or so, since the last raw farm.
Aim & fire vertically at the patch as before (Flak / Adv. launchers / however you prefer to pop the brain berries)
Reverse vertically to 600-1000m (Whatever's your magic number sweet spot for mesh culling & limpet range) - YMMW, bit of experimenting helps
Pitch to 0, open cargo hatch, clear target & deploy limpets (leveling pitch to 0 seemed critical vs. before, much fewer limp deaths)
Enjoy the ambiance while the wee dudes buzz around
Side note: the standard collector limpet controllers seemed to work much more reliably; universals, mining, op etc ones mostly just wanted to orbit about the hatch and not give a damn about unmarked loot. Or, the just crash and die.
As for the ethics: yeah sure if you feel like this being borderline kooky for your taste, there's always the SRV harvesting method, Dav's hope rally + crosstrade, pirate mission farming etc. But OP specifically asked for the state of the method in question so here goes & went. Hope it helps. Less grind means more fun at actual gaming <3
