In Bazel parlance you would write a "rule" or setup a "toolchain" which has the linker args passing setup in it. 99% of code does not need a specific linker arg though and optimizing the happy path for letting you do anything, rather than having a simplified flow that most users care about, makes things more confusing. If you instead had a way to say "this one specific thing I am building is special and needs `$magic_extra_arguments` added to it" and the rest of your code is "normal" things will be pretty good.
