It's a burden in the sense that it's another item of extremely limited utility that has to be modified in the continuing quest to modernize the NetBSD networking stack.

As for use with embedded systems, I can't imagine that it's really all that useful in that scenario; many of the UARTs on such devices lack flow control signals, so the reliability of the interface would be of concern.  There are typically (and, these days, universally) better ways to connect to embedded systems.  Honestly, the first thing that leapt to mind for a contemporary use of SLIP was "some poor soul might have a VAX 11/7x0 that without an Ethernet interface".
