I've got a ~9k loc Bevy "game" I'm writing that doesn't use dylib and takes > 20 secs every update, purely because of the linking (I'm not using mold yet, but am using lld)...

i.e., I type 'cargo build', it compiles the single .rs I changed almost instantly, but then I'm staring at:

Building [=======================> ] 314/315: landscape(bin)

for the next 20 seconds.
