In my experience, the only time I do this is with files that have been provided explicitly for my shell of choice. The only exception to this that I see regularly is shell installers auto-adding some directory to the PATH env by making automated changes to bash/zsh confs in $HOME. This may be a slight annoyance for some, but tbh I like it as having to manually paste in a PATH addition myself allows me to audit them (and it's still quick enough).
