There was actually a need for this in Record and Tuples' deep properties. You can see a bit of the discussion in https://github.com/tc39/notes/blob/af7d3c84524579e124649b1df891503e19b1d0ea/meetings/2020-03/april-1.md#record-and-tuple-update, where we talk about deleting a prop from some deep record.
You might try discussing this on the R&T repo, since they'd be able to champion it.
