Possibility of enabling structs for truffle-v5 target?

Based on this comment (and my own experience using the tool), structs do not get compiled for the truffle-v5 target: https://github.com/ethereum-ts/TypeChain/blob/f63bbe3504bb82eec2d683850998d8547b05f825/packages/target-truffle-v5-test/test/DataTypesView.test.ts#L35

I'm wondering what would need to change to permit struct generation in truffle-v5 and whether it's possible to reenable this feature. Thanks!
