The restriction is imposed by the kernel module and the code is still in the latest kernel. AFAIU, MPLS actions should always go before VLAN actions, otherwise the kernel will reject the flow. So, you have to push VLAN after pushing MPLS and pop VLAN after popping MPLS. And that doesn't really allow you to use VLAN and MPLS together. I suppose, the original explanation from Jesse still applies.
