Suggested change

	function ranef(m::LinearMixedModel{T}; uscale = false) where {T}
	function ranef(m::LinearMixedModel{T}; uscale = false, named = nothing) where {T}
	if named !== nothing
	Base.depwarn("the `named` keyword argument is deprecated; it has no effect", :ranef)
	end

This avoids making a breaking change, since user code currently calling ranef(...; named=true) will error if the argument is removed.

[palday]

This is queued for 4.0, which has other breaking changes.... but this would provide increased backwards compatibility (as most of the breaking changes are in the internal representation that the average user won't touch)

[ararslan]

Yeah if it's queued for a breaking release, might as well break it 😄
