Description

Issue Description

In #1880, questions were raised regarding the maintainability of the example build backend dependencies. Specifically:

  • how to handle backends that recommend upper bounds on the backend version (while tools that create per-package build environments can handle those without issue, they are a potential problem for build systems that aim to create unified build environments, such as those for Linux distros and from-source stack building projects like fromager)
  • how to ensure we're not recommending excessively outdated versions of the backends

Some flavour of automation could help with the latter problem, but the former problem is a trickier one.

Research direction

Read the “Declaring the build backend” guide section and the linked #1880 discussion first. Compare the documented backend specifiers with the two maintenance concerns in this issue; done requires a decided, maintainable approach for version bounds and avoiding excessively outdated backend versions, reflected in the example.
