We should take into account that in the "hack" we specify a hard coded bootstrap committee during several epochs. And if we remove it in the issue #1646 we could...

It is happen in the first superblock afer Superblock 0, the default current (empty) moves to previous and it is assigned a committee size of 0

There are some proposal in #1385 and #1737 but they imply some problems for now (so they are currently closed)
