It is pointless to argue about personal style preferences.

In any case, in my experience, this kind of changes is quickly made
futile by future changes to the manuals that re-introduce comma-less
e.g. and i.e. back into the text.  So if we want to adhere to the
style that prefers the comma, we should IMO install some change that
enforces these rules, to be run at "make info" time and flag any
deviations.
