It allows for managing load order and now the Vortex plugin supports it so in essence you install the DLC on steam/gog and you don't need to bother with anything really just use Vortex.
I would say the reasons to use it:
- It's maintained properly by CDPR so you can expect it to work out of the box with every update.
- You can play without mods with 1 click if something breaks
- Load order
- Doesn't affect CET etc. because they play along nicely
- Has a cool name
- REDmod sound mods for example only work with REDmod which you can do with CET etc but it is much cleaner this way.
So all in all, it's a tool and you have to decide for yourself how you utilize it
