It really isn't though. PCC just walked the AST, writing out text to a file with hardly any optimizations just like most of what people call 'transpilers'. But you wouldn't call a c compiler to asm a transpiler, right? Pretty much everything that gets attributed to some intrinsic difference between source-source and source-machine compilers is just a function of the immature tooling on the web.
