I suspect it's not worth the effort for most people. People who want to DIY a switch are likely content to brute force it with a decent cpu, multiport network cards, and lots of PCIe lanes. While others will be happy with a used enterprise OEM unit.

Does make me wonder what asics Microtik is using under the hood though...

A lot of them are just networking SoCs with built in switching fabrics or the lower end ones have the low end router SoC from various manufacturers.

Mikrotik is one of the few brands that actually list this in the spec sheets.
