Right, back in the day the main challenge was just to do what you wanted to do within memory and performance constraints, especially when trying to run a compiler on the target system as opposed to cross-compiling. This kind of super-sophisticated code generation, making the compiler itself larger and more memory hungry, just wasn't an option. This is a super hard-core hobby project! The 6502 is a great CPU, at least if you are hand-writing assembler for it, but a poor target for high level languages and difficult to generate high quality code for due to the extremely limited number of registers, quirky addressing modes, and lack of regularity. It's great to see the 6502 getting some love, even if it's 40 years too late to be very useful!
