You can use the same pattern (calling executeReport and sendEmail) still in 8.0.16, but there’s no great place to ‘house’ your script.
To get access to the convenient scheduling of reporting, you could create a ‘fake’ report (or ‘fake’ schedule) that doesn’t actually do anything, just runs a script action at a particular time. Or you could make a gateway timer event that runs at a consistent rate, and checks if it’s the ‘right’ time to launch execution - effectively the same as a scheduled script, just a bit harder to set up.
