All of the above.
This list is specifically what IS different or added. And when Asus implements one of these (or a variant of it) into the stock firmware, I either remove it from the list, or move it to a separate section listing what used to be on that list, and is now available on stock firmware, as seen on the website:

Didn't realize most items on the feature list are still exclusive to asuswrt-merlin. The following features are essential to me:
- User scripts that run on specific events
- Cron jobs
- Customized config files for router services
- LED control
- SSHD
They make my AC56U terrifically more useful and extensible. It's no brainer to flash merlin over stock.
