Base.repeat for numerical arrays vs. Base.kron

Question

I recently came across extending some of the numerical arrays that I work with along different axes and in different orders, and the repeat function of Base using inner and outer came quite handy. However, it seems like the kron function is extremely faster and more memory efficient. Is there any way that a more general function like repeat use this functionality. I understand that the repeat is not limited to numerical arrays, but wouldn't it make sense to use this functionality?

function inner_repeat(
    X::AbstractArray{T, 2},
    K::Int64,
) where {T <: AbstractFloat}
    return repeat(X, inner = (K, 1))
end


function inner_kron_repeat(
    X::AbstractArray{T, 2},
    K::Int64,
) where {T <: AbstractFloat}
    return kron(X, ones(T, K, 1))
end


Xs = [rand(10^i, 10^i) for i in 2:4]
Ks = [i for i in 2:4]

for X in Xs
    for K in Ks
        println("matrix of size $(size(X)) with $(K) repeats")
        println("using repeat:")
        @btime inner_repeat($X, $K)
        println("using kron:")
        @btime inner_kron_repeat($X, $K)
        println()
    end
end

And the output results are as follows:
