> I found this interesting insofar as it is somewhat rare for endpoint CPEs to have these features baked in, in particular with any sort of CALEA semantics.
This isn't targeting CPE equipment - MicroTik is baking into their unified OS. If you're a service provider you don't configure CALEA in the CPE, you configure it upstream in the headend where all traffic from your customers egress your network. It's much easier to grab it all at the bottleneck than to have data streaming over your expensive last mile twice for each customer, that doesn't make any network architecture or OpEx sense. It's just easier to make CALEA a function of RouterOS vs target specific models. There's nothing specific about the hardware that's required to implement the functionality.
