Do we really need to have ExponentialFamilyManifolds.jl as dependency?

[Nimrais]

However right now, we have a really mild constraints https://github.com/ReactiveBayes/ExponentialFamilyProjection.jl/blob/main/Project.toml#L32 it looks for me that we just do not need it here as dependency.

We use it only in two places

get_projected_to_manifold(prj::ProjectedTo) =
    ExponentialFamilyManifolds.get_natural_manifold(
        get_projected_to_type(prj),
        get_projected_to_dims(prj),
        get_projected_to_conditioner(prj),
    )

function preprocess_initialpoint(
    ::Type{T},
    initialpoint::ExponentialFamilyDistribution{T},
    M,
    parameters,
) where {T}
    return ExponentialFamilyManifolds.partition_point(
        M,
        copy(getnaturalparameters(initialpoint)),
    )
end

So maybe it's a reasonable solution is to create ExponetialManifoldsBase.jl define these two interfaces there and use ExponentialFamilyManifolds only as a test dependency.

I don't see this as a problem. Using it in only two places isn't an issue because the library is already small. Creating another Base library doesn't seem to offer any immediate benefits. What specific problem are you aiming to solve?
