  That sounds extraordinarily unreasonable to me.

  If the unit file is broken with bad input it is broken - it is not
systemd's job to detect/fix bad input to an application - it should do
what it is being asked to do and run it as per the inputs in the file.

  If the application fails due to bad input then systemd should (and
presumably does) report the failure that the application itself reports
to systemd.

  Systemd cannot possibly know what valid arguments and syntax are/might
be for every application existing and not yet written - and should not.
Thats the job of each application itself - to exit with an error if the
inputs are bad and then systemd should report that error information.

  systemd does enough - leave it alone :-)
