It isn't. A sizable fraction of all software development is done for devices 
with under a megabyte of RAM. (IoT and embedded are huge markets.)  And 
remember, we're talking on the email forum for a library that's heavily used on 
that scale of hardware.

And even on bigger systems, L1 and L2 caches are small: Intel's i7 Haswell CPUs 
have 32KB and 512KB per core, respectively. Remember, "overflowing cache" is 
the new "VM thrash" — RAM is absurdly slow compared to CPU speeds.
