I think only benefit to regular switch here is unique VLAN and even
that is not true, if switch knows VLAN rewrite. It'll also decouple
the devices, so you don't have to upgrade them at the same time. And
certainly will expose you to fewer issues.

It does not act like normal router port the more deeply you review
them. For example LPTS is way too aggressive for satellite, as all the
ports are just single port to LPTS. QoS also is not at all the same.

I see this is same for Switch.

This is benefit, but only if you're provisioning by CLI jockey.
