A number of things. The biggest one is probably compressed instruction sets, which even x86 "CISC" processors use.
For example, RISC-V and Thumb use this in their processors and they're a big boon.
Also, I think that you've been lied to about the relative code density of RISC vs CISC. CISC is only about ~50% more dense than RISC in the best cases, unless you're talking about polynomial evaluation on VAX or something crazy like that.
