Maybe the ICC should start adding a reserve day, in case more than 180 overs of the match gets washed out? Due to the COVID pandemic, a number of bilateral tours are now being played in off-season, and this increases the risk of washouts. Also the global climate change is resulting in increasingly irregular weather across the globe. The broadcasters are losing money, but the cricket boards themselves are not directly affected. At this point, the minimum that the ICC can do is to add a reserve day.
I think the ICC should add reserve day. Because if the matches are not broadcast, the broadcasting TV channels are damaged. And these broadcasting TV channels are a major source of income for each board. So the ICC should keep a reserve day in each series even if it thinks of the broadcasters.
I wouldn't suggest any reserve day for the test cricket, majority of test playing nations struggling to generate enough revenue and they are always in loss when they schedule any test series, 1 extra day would hurt their economic model more, this is one of the main reason some cricketing board were trying to reduce 5 days cricket to 4 days. Although this doesn't apply to PIG-3 bilateral series or when India play with other member.
IMO The best possible solution would be some kind of mutual contract between PIG-3 (no interference from the ICC), they have resources so they can afford extra day for their bilateral series, these series generate enough revenue. Schedule can posses some challenges but it looks manageable if we dig deeper. for example rotation policy for players, 2 different team for Tests and LOI etc.
