Design question (probably not directly related to this issue):

Templates that accept EncodingBuffer and EncodingEstimator are declared as:

template<Tag TAG>
size_t
wireEncode(EncodingImpl<TAG>& encoder);

and instantiated as:

template
size_t
wireEncode<EncoderTag>(EncodingImpl<EncoderTag>& encoder);

template
size_t
wireEncode<EstimatorTag>(EncodingImpl<EstimatorTag>& estimator);

An alternate is to declare the template as:

template<typename Encoder>
size_t
wireEncode(Encoder& encoder);

and instantiated as:

template
size_t
wireEncode<EncodingBuffer>(EncodingBuffer& encoder);

template
size_t
wireEncode<EncodingEstimator>(EncodingEstimator& estimator);

What's the rationale of choosing the first over the second?

The reason I chose to use "bool" as a template parameter to guarantee that there can be only two versions of this method in existence: one with true and one with false.
