The plugin was a request, the crontab plugin can indeed do anything this plugin does (and much much more).
Consider this the lean and mean version for people who just want straight up daily config files without having to deal with a plugin that has multiple configuration files and features/terms many people aren't familiar with.
If you want more freedom and options, go for the excellent
Server crontab plugin. If all you need is a monday.cfg this might be the simpler choice.
