Research direction
Start with the linked R-Forge report and the code handling .SD and dropfactor. Determine how dropping levels for many small groups could avoid repeated level copying, then verify that the behavior is optional and defaults to FALSE. No specific files or tests are named in the issue.

Description
Submitted by: Matt Dowle; Assigned to: Nobody; R-Forge link
This is for many small groups, where dropping the levels in .SD, means the result doesn't have the levels copied over each time, and as a result can be faster. Optional, default FALSE, for advanced users.
