On clients that follow the spec properly, that will *override* the
default routes so they will have a route to 192.168.3.0/24 but no
default route.

You need to include the default route too, for example (assuming that should go via 192.168.2.254),

option classless-static-routes 192.168.3.0/24 192.168.2.1, 0.0.0.0/0 192.168.2.254;
