You do realize you have the exact same chances with an environment entry line do you not?
The options being used there could be deprecated in the daemon startup and for those daemon/services that are capable of reading their own configuration files ( and thus those environment lines are not applicable to ) are never changed on updates..
When an administrators makes a change to an configuration ( or in this case type unit ) he is stating that he's deviating from the distributions shipped defaults for that components and since there is no reliable way for a system to detect and determine manual changes in configuration, there is always the risk that an update will break running system ( the administrators made changes ) which is why the configuration files for a running daemon/service are saved as copy's and the administrator who has made the deviation is expected to review and apply those changes himself.
