Python JIT compiler project under threat after steering council says proper process wasn't followed

No new features to be submitted to main branch, existing code removed in 6 months if new proposal not created and accepted

Why this matters
Why now

The Python community's steering council is asserting governance over core development processes, particularly for significant performance-enhancing projects like a JIT compiler.

Why it’s important

This highlights the challenges and bureaucratic hurdles in evolving foundational open-source projects, which are critical infrastructure for much of the technology world.

What changes

The development trajectory of a significant Python performance improvement is now halted or significantly delayed, requiring a new governance proposal.

Winners
  • · Python core developers (focused on process)
  • · Alternative JIT projects (if this one falters)
Losers
  • · Python JIT project team
  • · Developers awaiting performance upgrades in Python
Second-order effects
Direct

Further delays in Python's core performance improvements, potentially impacting its competitive standing against other languages.

Second

Increased scrutiny and formalization of development processes within other major open-source projects as communities grow.

Third

Potential for a fork or creation of a new, faster Python implementation outside the direct governance of the current steering council.
