I've not seen any feedback on my "counter"-proposal: switch jit_tuple_deforming to off by default. Sure, for the
perfectllvmjit use cases this will reduce the performance benefits, but it will remove most if not all the problematic
queries(for instance queries running on many partitions, adding/moving columns leading to explosions in compilation
time...)
Of course if there are other troublesome situations, I would love being proven wrong.
