Zimbabwe Cricket head Peter Chingoka declined detailed comment but said "It's just a proposal."
The overall angle of the document is that cricket, especially test cricket, is often not financially viable outside of the big three countries.
Instead of the Test Championship, the two lowest-ranked of the 10 test-playing nations -- currently Bangladesh and Zimbabwe -- would be relegated from the format next year and have to fight their way back up to the top division through the four-day Intercontinental Cup and then a playoff. If a relegated nation doesn't win back its place in the top tier on the first attempt, it would lose money from the ICC.
The proposals do offer associate members Afghanistan, Canada, Ireland, Kenya, the Netherlands and Scotland a chance to play tests through promotion, and a test cricket fund would give money to Bangladesh, Zimbabwe, New Zealand, Sri Lanka, Pakistan and West Indies.
