Crate splitting required for reasonable compile times fragmentizes code organization

6/10 Medium

Developers must split projects into many small crates to achieve reasonable compile times, since crates are compiled as single units and circular dependencies are allowed. This artificial fragmentation complicates project structure despite most code lacking true circular dependencies.

for reasonable compile time you need to split projects into lots of small crates... crates are compiled as one compilation unit... most code doesn't actually have circular dependencies so why not make those opt-in?
