This style of delivery is not wonky at all.  It's standard for most
types of dedicated connections: T1, DS3, Metro Ethernet, etc.
It's been this way for decades.  The /30 is for the link between your
router and the ISP, and your own granted subnet is for another
interface on your router, the local side.

The only Comcast product I would not recommend is any of their
Ethernet over Coax stuff, used for maintaining a private link between
a fiber site and a coax site.  That is still slightly buggy.  But
their other stuff: normal business coax, fiber internet, or fiber
private lines are all good.
