All two node clusters I remember run with setting forever :)

"better" us subjective, but ...

That is what stonith does. Because quorum is pretty much useless in two
node cluster, as I already said all clusters I have seem used
no-quorum-policy=ignore and stonith-enabled=true. It means when node
boots and other node is not available stonith is attempted; if stonith
succeeds pacemaker continues with starting resources; if stonith fails,
node is stuck.
