IMO, it would make sense to just install files in a directory and only have
.zshrc source them all (either using a well-known ordering mechanism or
implement some fancier dependency system).  Then you don't need a brittle
mechanism to edit (multiple times, and then to maintain the lifecycles of those
edits) a file that's nominally under user control, other than to insert a single
line.
