There wouldn't be any need for a CONS-LIMIT,
because individual conses are always the same size,
But what if I wanted to write a program for, as you say, an embedded
system, and I needed to know exactly how many cons cells I can create
and be quite certain that I won't run out of memory? Conversely, if I
know what the bignum limit is, and I stay within that limit, but make
zillions of such legal bignums, then I might run out of virtual memory.
So whether the individual object is of fixed size or of variable size
doesn't really matter, for the purposes you're referring to.
