RouterOS only supports EVPN+VXLAN on Type 4 routes. What's missing for Type 5?

RouterOS General

This topic involves L3VPN, Hardware Offload, and VRF.

Right now, MikroTik's official documentation is in transition. And I couldn't find it, but I'm sure I've seen somewhere that RouterOS's EVPN+VXLAN support is limited to Type-4 routes. In other words, at this moment the scenario is an L2VPN on steroids.

And the main steroid is that VXLAN accepts Hardware Offload.

One point that is clear is that RouterOS does not support Hardware Offload of MPLS encapsulation, such as PE devices.

We also know that in release 7.24.beta1, support for VRF with hardware Offload was initiated. But it still doesn't cover any encapsulation mechanism.

Given this, we can say that at this moment MikroTik does not have a solution for high-traffic L3VPN.

I'm not an expert in architecture and hardware, but I understand that the LSI of a VXLAN is a VSI of a VXLAN... What it points to is essentially route pointing (whether Layer 2 or Layer 3 routes).

Given this... I'm trying to understand if there are any technical architectural impediments for MikroTik to implement L3VPN over EVPN+VXLAN using Route Type 5.

I think there is also this issue that would make an implementation fn L3 routes less useful (cite from docs):

Hardware offloaded VXLAN:
[...]
Routing between different VXLAN VNIs is not supported.

I would still love to be able to insert type-5 routes from external networks where this isn't an issue, but alas.
