The decision to demote the i686-PC-windows-gnu target to Tier 2 reflects a move towards focusing on more mainstream platforms due to the limited demand and support for 32-bit Windows systems. There is concern among developers about the quality of support and potential bugs that arise from less commonly used targets. While there is still a small community using these older architectures, the focus is shifting to more robust platforms. Furthermore, this transition may influence other operating systems, such as OpenBSD and NetBSD, to reconsider package support as Rust gains traction. This could lead to challenges for developers relying on older hardware and spur discussions about the future of software development on legacy systems.
