I think the default Strava maps should have indications of the direction of travel. This is important for overlapping/intersecting routes, and especially loops. It would be particularly helpful for shared routes, where you may have no idea which way to go. But also good when looking at others maps (e.g. did they go up or down that section of the hill?).
Many other mapping solutions have this inbuilt and it can be unobtrusive. For example, AllTrails does this well. See image, you can clearly tell that the trail goes north, not south because of the little chevrons/arrows.
Perhaps this could be optional, but I don't see why anyone would want to hide the direction of travel if they are sharing their map already.
While you're at it, adding mile/km markers (optional setting) would be very helpful, paricularly on Route maps when you are trying to plan out when to refuel, etc.
