Can we use 1 and 0 for TRUE and FALSE to reduce wire size?

[wilaw]

This would apply for all keys which carry BOOLEAN values.

Invalid request since BOOLEAN MUST omit that value when serialized.

[littlespex]

true values are omitted, false values are already compacted as ?0.

Parameters whose value is Boolean (see Section 3.3.6) true MUST omit that value when serialized. For example, the "a" parameter here is true, while the "b" parameter is false:

Example-Integer: 1; a; b=?0
