In static route they are also, ARP timeout in JunOS is 20min by default, so
it'll just take quite long time to invalidate the static route (short of
bugs like the OP sees)

Cisco has 4h, which is absolutely ridiculous.

Linux uses 1min, which is better than default BGP holdtime in Cisco or
Juniper. So statically routed Linux would converge faster than BGP routed
Juniper in sudden disappearance of peer.

Of course both ARP timeout and BGP holdtime are tunable as well as either
BGP or static could run BFD.
