Currently, the bit allocation within the leading encoded byte is `0bTVVV_VVVV`. In practice in the Polkadot ecosystem, the leading byte would be `0bT000_0100` as the version has been equal to `4` for a long time.

This RFC proposes for the bit allocation to change to `0bTTVV_VVVV`.
This RFC proposes for the bit allocation to change to `0bTTVV_VVVV`. As a result, the extrinsic type bit representation would change as follows:

| bits | type |
|-------|-----------|
| 00 | unsigned |
| 10 | signed |
| 01 | reserved |
| 11 | reserved |
