For Python packages specifically, isolated environments are expected and
practically required. There is widespread dependency version bounding and
pinning and excepting for various different reasons. In a pure Python
environment, both pip [0] and build [1] build binary wheels in an isolated
virtual environment by default. There was a proposed standard [2] to make
virtual environments mandatory; while withdrawn for different reasons, the
sentiment remains that virtual environments are an essential part of the
development workflow, binary wheel building included, to the point where
higher-level tools wrap them. [3]
