I am thinking to return a brand new 28-70mm f2 RF lens

The f/2.0 zoom doesn't replace primes and doesn't replace light weight zooms.

1. You will need primes when you want less weight with a large aperture. If you have bot the f/2.0 zoom and the 35mm f/1.8 prime, there's no redundancy.

2. You will need primes when you want an even larger aperture. If you have the f/2.0 zoom and primes like the Sigma 28 and 40mm Art or the RF 50mm f/1.2, there's no redundancy.

3. You will need another zoom when you want less weight and the ability to zoom. If you have the RF f/2.0 zoom and the f/4.0 L zoom, there's no redundancy.

This!

Basically there is a good justification for having most lenses. At least I usually manage to find one! 😀😆

That is how I ended with 25 lenses!! I have 8 RF lenses but no 28-70f2. I have RF50f1.2 (excellent prime and best Canon 50mm ever IMHO) as well as RF 70-200f2.8 which produces plenty of boken at 200mmmf2.8. I prefer the adapted EF85mmf1.4L IS for indoor sports action (it is fast focus) and sometimes for portraits but I have other 85mm f1.4 and 1.2 lenses that are not as good as the 85mm1.4 IS for focus speed and heavier that I acquired over the years for head shots but they all slower in focus speed if the subject is not moving. The Sigma 85f1.4 ART is good for boken and plenty sharp corner to corner and the EF85f1.2L MK II is sharp in the middle and has plenty of portrait character but it is a slower for moving subjects and run and gun shooting than the EF85f1.4L IS that is sharper in the corners and much faster focus.

I would think my hypothetical event shoot use of the RF28-70f2 would be better served by some combination of my RF50f1.2 for localization and extreme edge to edge sharpnes and my RF24-70f2.8 but that me and it would all depend on the venue and how close to location alternative lenses were being kept.   Part if my concern is f2 is a compromise for localization and not as shallow as f1.2 or f1.4 that also create risk of being too shallow in some cases and time consuming or impossible to achieve with excellence at even f2 when there are two subjects at tending to be slightly different distances and f2.8 can be better.   There is no perfect lens but there are plenty of heavy lenses to choose from.
