Stagger the joins, but a 1/4" tongue of weetabix doesn't have much
strength, so only tread where you can see screws into the joists
unless you're slimmer of the month ...

Do you take similar care walking over a floor in a modern house?
Because the same arrangement of floor boards exists there.

Remember you are talking about a 2' wide board adjacent and interlocked
with another, spanning one joist space - so there is no reason for it
to give at the edge.
