> Currently `USEMODULE` is appended using `+=` which makes it recursively expanded.

This is not fully true. The behavior of `+=` depends on what the variable that gets appended to: If the variable existed previously, it will keep its "flavor", e.g. a simply expanded variable will remain simply expended. However, if the variable is undefined, it will be defined as recursively expanded.
