Hi Paulo,Hi Jan,
You have a long and storied history in shooting.
If I were in your position I'd get a used babied copy of the lens that is being sold at a great discount because everyone's in a rush to move to mirrorless.
I am fairly certain the RF equivalent will be released within 4 years will delight you always.
Unload the EF copy at the equivalnent of rent expense of less than 4 years.
It is a herculean task to output 8 new lens SKUs per year for the past 4 years & the next 4 years.
Canon & Nikon need to match Sony's lens system. That was the selling point of their EF & F mount.
If I were starting from scratch to do bird work I'd opt for the Nikon Z system because their lenses are lighter on the back & in the back pocket.
But like you I have concerns about relearning how to ride a bike with the different physical button placements & menu system other brands use.
This is what I discovered with the 2015 Sony a7R II & my worry with the 2021 FujiFILM GFX 100S medium format
BTW how do you like the 2021 EOS R3 for bird photography? I would like to hear your thoughts on it.
I have been photographing birds since Jan 2009 with an
I provided links for you perusal.
I copy pasted your site and your body of work is worth emulating.

Sorry but I did not explain my predicament sufficiently.
I do not do bird photography. What I most enjoy shooting is car racing. Someone showed me that the Sony Alpha 1 was great for bird photography, so I just assumed it would be great for car racing photography also. That is why I switched from 50 years of shooting Nikon to the Sony Alpha 1. I should have tried it before selling my Nikon gear, because after using it for three months, I concluded that its autofocus system was not very good for shooting car racing. That is why I switched again — this time to the Canon EOS R3. Its CAR MODE AUTOFOCUS is GREAT for car racing photography. I have no idea how good it is for bird photography.
