Ever since Ex has not been in AtCoder Beginner Contest, it feels like every contest has changed too drastically compared to when Ex was in ABC. The difficulty gap between E-F-G has become much, much wider. Previously, we usually had a choice between whether to solve F or G, if we are stuck in either one of them in occasion. Now, we do not have that choice, as the tasks that used to be at Ex is now at G. I think this is a huge loss for people who could solve until F, because they often lose an entire task to solve. There are many other issues, though I will not enumerate every single one of them.
I understand the current situation, the lack of hard tasks and everything. I know how hard it is to hold a contest with a problemset of 8 tasks every week. However, couldn't we have found a better solution to this hard situation? Instead of removing Ex from the problemset, a Call for Tasks can be held, similarly to how it is done for AGC. If I am not mistaken, AGC Call for Tasks requires that a whole problemset is prepared (similarly to contest proposals on Codeforces). For ABC, if easier tasks are abundant and we are in a lack of harder tasks, a Call for Tasks on separate tasks aimed towards G/Ex can be held. This can effectively alleviate the hard situation we are currently in. And this will be effective as well for people who would be willing to set problems on ABCs, but could not because there was no opportunity.
I hope you could consider this suggestion quite seriously.
