Wow, interesting, and thank you (this is very useful to know)! I was
just reading yesterday about pure-unpure containers in Lilypond,
trying to figure out some possible use cases.

I think I've encountered a similar issue during the years, but I had
no idea what was the reason. I (think I) never asked for help here
thinking it's a bug and ended up instructing Lilypond to put less
systems per page or modifying the layout, staff size, etc. I
personally use a lot of brackets and in general there are many cases
in which the bracket shouldn't be omitted. Is there any technical
advantage in not having estimates for the brackets?

Cheers,
