True, though /proc/cpuinfo only reports the size, which is ultimately what the CPU cares about. Plus the most relevant limit is what your motherboard and wallet supports, which is often far lower.

Indeed, and as you say, sensibly speaking you are hardly likely to hit those limits in any likely (esp. home) setup. The actual meaningful limit is usually the CPU physical one as home CPUs very often have stringent memory limits (often 32 GiB or so) and of course you rely on the motherboard's limitations also.

Having said that I did write a patch to ensure that the system would boot correctly with 256 TiB of RAM [0] so perhaps I am not always a realist... or dream of the day I can own that system ;)

You're not the only one dreaming; I had to use >200GB of swap on my home system last year.
