No, I mean it's a common characteristic of toy languages to use Boehm GC because it requires zero configuration to work, as it scans conservatively. It doesn't require you to emit stack maps or provide the GC with type metadata. Boehm GC means low effort (in regards to memory management). It's perfectly fine to use it, and it's an amazing library itself, but it contrasts with all the claims on the landing page (in the section "innovative memory management").
