Have you checked out Warp drive for zsh? https://github.com/mfaerevaag/wd It is more manual than z, but takes out the learning phase. Will check out z though!
It depends on how you work, I have a lot of small projects which come and go, so setting up the paths every time I start or finish something would be inefficient.
Although I might adopt it for different weird system configuration directories which I often forget the path to.
Yes I have had that problem already, more specifically cleaning the lists in wd if directories are moved or removed. I do a cronjob to try to rectify that but interested to see if z mitigates this problem - seems there is an option -x to remove learned directories.
[edit] Or z's based ageing ranking system will just aged those legacy directories, even better (in terms of more hands off)!
