If I end up swapping out this lens, it will probably be for the new RF 15-30mm f/4,5-6.3 IS STM, and not the 14-35L f/4. I do not use a UWA lens enough to justify the cost of the L, and also like having a smaller & lighter lens. My previous EF 16-35L f/4 was relatively big and heavy for something I didn't use much.
I plan on hanging onto the RF 16mm f/2.8 for now and will see if I miss having a UWA zoom. This is the first time I have went with a prime-only solution for UWA. It sure makes it easier to pack for a trip, though. I have my EOS R with RF 24-105L, RF 100-400mm, RF 16mm f/2.8 and RF 50mm f/1.8 all packed in a small shoulder bag for an upcoming trip. With my previous EF 100-400L II and EF 16-35L f/4, I would have been taking the much larger and heavier backpack -- or taking my EOS M50 kit if I wanted to travel very light.
I was originally excited for that 15-30mm but I’m just not sure about it now due to the aperture on the long end. I tend to use these zooms as general purpose sometimes like family events so that f/6.3 could be an issue. Since you got the 24-105L, I think the 16mm prime is fine for you then!

I still have the EF 17-40L. I don't use it much so probably can't justify another high priced wide zoom. I also might look at the new 15-30 some day. I have used the EF Tamron 15-30 a couple of times and liked that one, too.
For now I'm staying put, until (if ever) I start using the two wide angles more and more.. Also like Scott I like the size and compactness a lot since I usually travel with two large lenses, this one adds almost nothing to the backpack.
The size and weight definitely are nice on the 16mm. I used to primarily use a UWA zoom (RF 16-35mm) or a 35mm prime, but in recent years I’ve favored tele lenses more so haven’t used a UWA as much either.
15-30mm seems best for most, I just wish it was a constant f/4.
