You may never have a problem with your fuseable link. But if you did it isn't likely to be convenient.
But with your increased amperage from the alternator you could end up in a situation where the battery is charging at a higher rate than the fuseable link can carry.
Or if the engine wasn't running and your fans, headlights, wipers, heater, radio and such were on and you tried to start the engine you could draw more current from the battery than the fuseable link can carry.
When starting the engine the system voltage will drop and thus amperage will increase at every load. It's that Ohms law thing.
At the minimum I would recommend carrying a spare fuseable link or two so you won't be stranded if the worst happens.
