Is there a reason `rand(TDist(nu))` does not obey the type of `nu`?

Hi, it seems that

nu = 3f0
rand(TDist(nu))

returns a Float64 instead of a Float32. Is this intended behavior? I find it unusual because the rand implementation tries to be type-stable half way there by using one(T) but ends up calling randn(rng) without specifying the type.
