Currently, bitset consumes at least 4 bytes:
This is a penalty for users who want to use a small bitset as a more-strongly-typed replacement for a small integer.

Research direction
Start by reading stl/inc/bitset around the linked lines to understand the current minimum storage layout. Determine the constraints for reducing storage for small bitsets while preserving bitset behavior and compatibility. Done means a smaller representation is implemented and covered by the relevant bitset tests, though no specific test file is named in the issue.
