Layer 3 switching has been the de-facto standard in data centres for use-cases such as VXLAN/EVPN and for service providers i.e. MPLS/EVPN for more than a decade. These technologies allow data centres to scale to large numbers of devices and to isolate traffic between different tenants straight in the access layer using the spine-leaf architecture.
Unfortunately, MikroTik's current 'Layer 3' switches are not well-suited for these applications. They have limited routing table capacity, no hardware support for VXLAN/EVPN or MPLS, and relatively low performance. Therefore, data centre operators have no choice but to use Layer 3 switches from other vendors, such as Juniper and Cisco.
For an example point of reference, here's a switch that many DC operations and SPs around the around use for L3 switching, MPLS, VXLAN, EVPN at line-rate—The Juniper QFX5100:

This layer 3 switch supports a massive routing table, perfect for L3 switching and MPLS at scale:
• IPv4 unicast routes: 128,000 prefixes; 208,000 host routes; 64^4 ECMP paths
• IPv4 multicast routes: 104,000
• IPv6 multicast routes: 52,000
• IPv6 unicast routes: 64,000 prefixes
In comparison to MikroTik's current flagship switch CRS518-16XS-2XQ-RM, this speaks for itself, there is no Layer 3 switching benchmark:

The CRS518-16XS-2XQ-RM is not usable for production-grade layer 3 switching (even if MikroTik ROSv7 supported EVPN for MPLS/VXLAN).
Normis himself made it clear that MikroTik doesn't support layer 3 switching for scale:

Even worse are engineers or experts who somehow have yet to figure out that layer 3 switching is de-facto implementation for spine-leaf architectures, VXLAN/EVPN, MPLS/EVPN and yes, even Telco-MPLS rings:

It's a switch, so why should it compute routes (thousands of them)? How does "thousands of routes" relate to "distribution switch in smaller networks"? In my world it doesn't, in my world "distribution switch in smaller network", even if used as L3, switch, is about a few (less than 10) subnets with tens of hosts active in each subnet.
A high-performance Layer 3 switch from MikroTik would be a boon to the data centre and SP community. It would give operators more choice and would help to reduce the OPEX and initial CAPEX.
So bottom-line question as the tile suggests:
Why are there no production-grade L3 switches from MikroTik in 2023?
