Probably an oversight, I'd guess. As with many such situations, things that
aren't obviously and critically broken don't get much attention ;)
It is not really an oversight since all computers with a TCP/IP stack
need to deal with some level of routing even if they are not acting as
a gateway. If there is ever more than one way to get "there" via the
L2 network then running a higher-level routing protocol (e.g. RIP) can
help the TCP/IP stack make the right decisions if the involved routers
use the same protocol. The host might participate in RIP or it might
just act as an observer.
In many cases one or more computers are attached to a shared L2
network with a single upstream router. In this case, using DHCP to
configure the default route, or static configuration to provide the
default route, can be a good choice. There are other means such as
ICMP Router Discovery Protocol
(https://en.wikipedia.org/wiki/ICMP_Router_Discovery_Protocol) or even
ICMP redirects.
