That exactly why the PC was so successful for decades: it supported usage scenarios its designers didn't anticipate ("640k should be enough for everyone").
Part of my work is simulating and testing infrastructures. I do that with VMs, sometimes quite a few. So I use relatively low-cost hardware (NUCs + PC based workstations) with lots of RAM. And some of my laptops allowed for 32/40/64GB expansion, which helps with local demos and tests.
RAM in DIMMs is cheap, so cheap it's easier to just buy more than thinking about how to shoehorn a workload into less.
But that's changing when vendors can charge punitive prices on RAM capacity.
