The absolute nature of your blanket statement has no legs. It does with how
you use your PC and spend your money (the irony isn't lost that you aren't an ultra guy but still bellowing about 10GB not being enough, lol), but there are other ways to do so as I just explained. 'Always' simply isn't true.
I'm not holding my breath... consoles rock 13.5GB of a shared pool... RAM and vRAM... so it likely isn't those that are pushing more vRAM use. Sure it will go up with time, but as we've seen in a small cross section of game reviews here, there is literally one title that uses over 8GB of vRAM at 4K (IIRC, there may be two? - maybe that was 10GB, who knows, I'm not looking, lol). But I also addressed that point with allocation and use/what you will experience in the game as well.
They aren't though. Please read some of TPU's game reviews and focus on the vRAM use at 4K/Ultra. The ONLY reason 10GB concerns me on this card is if you run 4K, plan on using mods in games, and keeping this thing for more than a few years. Otherwise, you'll be fine for the next couple of years running Ultra or the next few with tweaking a few titles down. Still, the vast majority of titles will fit within the onboard vRAM buffer for years.
EDIT: It's too bad that the Radeon 7 would be a potato trying to run some titles at 4K Ultra/60... it's not an overall 4K 60 card at 8GB, nor at 16GB. Are there any titles that trip over 8GB at 2560x1440? So the R7 is a great example of too much vRAM for the appropriate res and not enough horsepower to use it at 4K. Over half the titles in the TPU review are below 60 FPS at 4K, a few WELL below that value and what many would call 'unplayable'.
EDIT2: For giggles, I looked through the last 10 of TPU's game performance reviews.. here are the accurate 4K values (max, some includes RT)...

I would say one title is very close (over 9GB) approaching the limit. The others, most, are not remotely close using 7.7GB or less. Maybe there are other titles that show more, but just giving 10 examples of titles that don't hit 10GB.... which happens to be the latest 10 titles he's tested. You can continue on down the list if you want.
