ODIs bilaterals might look boring to many but ODI wc is goated and still has lot of value among fans, some might even argue that it's significance is more than T-20 wc and rightly so.
This is exactly why they should limit the ODI format to the World Cup and nothing else leaving more breathing room for players to focus on the other formats. 3 formats together are pushing more and more players to retire early from one or more formats these days.
The ICC needs to prioritize all 3 formats in a better manner if they wish to stop this early international retirement trend soon.
What do you propose and how should ICC decide which format should get the majority of the schedule?
Considering the current scenario, white ball (t-20, odi) series generates revenue for cricket boards (home) and it means, the one we call irrelevant bilaterals is source of income for many and it keeps them floating and in some cases even subsidize few tests.
