8 years ago Zgen already supports this, you can set ZGEN_AUTOLOAD_COMPINIT=false if you don't want compinit to be called.
Compinit should only be called once, and it would make sense that zgen is the last thing that modifies fpath and should be the one to call compinit. I just submitted a pull request to omzsh to add an option to prevent calling compinit. It would be better if zsh made it possible for zgen to "hide" compinit as a noop, but if that's possible I don't know how to do it :)
You're right that zgen should call compinit -i -C -d "${ZGEN_DIR}/zcompdump" instead, since the whole point of zgen is loading a static configuration where our functions aren't changing.
You should submit a pull request with your lazy loading version, since sourcing zgen probably shouldn't do much of anything, and definitely shouldn't take more than 1 ms (currently everything before zgen-init on line 468 takes 20ms for me so I source the init file directly).

So, in trying to speed up my shell launch-times, I discovered that one of the slowest parts of my boot is zgen invoking
zcompinitwithout-uor-Cor anything:(My own
zcompinittakes nowhere near as long, as it's set-C, and I manually clear out the~/.zcompdumpwhen I have a reason to.)At the moment, I've accidentally fixed this for myself by lazy-loading all of
zgenitself, so thezcompinitis never hit at load-time … but I can't figure out why zgen would be messing with this anyway. Can this be disabled somehow?
