This might make sense IRL, but not in the game. The idea behind fishing is to get people out in the OW and give some life to it. I see it as a bonus when sailing for my regular travel, not as an end in itself, especially when the teleport to outpost will be disabled.
Personnally, I'll never use the feature anymore if it ever involve sailing around at low speed in designated fishing spot. IMO, the goal should be to discourage AFK fishing, not promote it.
