You mean from private to public?
In that case, you would just have to change a single package.
(also, if yes: does it happen often and is that really what we should optimize for then?)
Re: optimization, what does using casing instead of an explicit `pub` prefix optimize for, exactly? Compiler complexity? Typing ergonomics?
Can you explain that to a newbie in 2 sentences ?
