They are explicitly against configuration options though. Good luck if their opinions about what's sane doesn't match your own. By the way I have that feature in zsh myself. Quite useful.
I checked fizsh out and the installation on Ubuntu was broken (from the package in the repo), the last commit to the repo was in 2016... It seemed promising at first but these things are all about continued investment and maintenance.
Comparable functionality in zsh would be 500loc of ultra obscure tweaks :)
