Presumably they were working with a constraint of not spending much more on teaching overall.
If you kick out 10% of children, you then need to find something to do with those 10% of children, who are likely disproportionately in need of more individual attention to keep them on track. (I guess you could just declare them unteachable and useless, but you still have to do something with them and personally I’m not keen on writing people off without very good reason.)
If you reduce class sizes by, say, 25%, then you need 33% more teachers.
If (per waveman’s comment) you get rid of, say, 10% of underperforming teachers then (1) this affects only ~10% of children at any one time, which makes it hard to believe its overall impact would be huge, and (2) you now need to find a whole lot of new competent teachers, which for the usual supply-and-demand reasons means paying more per teacher.
I am very much in favour of being willing to spend a lot more on education, but it isn’t terribly surprising that these projects didn’t do that.

Have dedicated classes for them. Smaller classes help with that, because they are easier to keep in check.

The main benefit of class time is personalized attention from the teacher, not watching lectures or doing exercises (which you can do at home). The budget of such attention depends on teacher-hours, not class size. In fact, large classes waste it, because the teacher has to keep everyone in check instead of focusing on one student. So you don’t need more teachers—reducing class size and class time in lockstep while keeping teacher-hours constant would still be a net benefit. Heck, I’d experiment with reducing both by 5x, so we can have small skill-matched groups and each student gets a little bit of personalized attention and homework. That would be better than the usual situation of 30 kids waiting for recess.
Interesting suggestion. It’s not at all clear to me, though, that 5h/week of small-group time is really more effective than 25h/week or large-group time; it means a considerably longer interval between chances to get any sort of support on any given topic. And the children have to be doing something while they aren’t in those small groups—a major (though not always acknowledged) purpose of the school system is to keep children occupied in a reasonably safe way while their parents get on with their lives, so it seems like there would still need to be some kind of large-group supervision during the rest of the school week. How would you envisage this working out in practice so that it doesn’t end up costing twice as much as the system we have now?
Yeah, I don’t have a realistic plan for school reform :-) But if we’re talking wild speculation, let’s cut class size by 4x, cut the school day by half, and cut school years by half! Make it 3 hours per day for 6 years, most of it spent interacting with teachers. (Plus homework time.) Everyone in my family would be ecstatic with this, kids and parents alike. And I don’t think any child would need daycare after finishing this.
