Welcome to the community 
It depends whether you see WK as a one time go or more like a tool to add to the tool box. There are reasons for advanced Japanese learners to do the one or the other (and we have both groups here in the forums).
You already addressed that future is unknown and sometimes RL catches up. Also keep in mind that WK kind of implies users will read along a lot. The idea is to have additional exposure to make the vocab and kanji stick.
I’ll give you a couple of threads for reading, written by people that already hit level 60 and went full speed or have been advanced learners already when they started WK. All of them are still active in the forums so feel free to ask them as well in case you have more questions
