We handed new devs the ELF spec, the PE spec, and the MachO spec. But we were doing low level work that integrated our SDK into already built binaries.

I've run into problems in the past with namespaced classes not raising link errors for duplicate destructor definitions. That took us 2 weeks to track down.

In any case, at the moment it's mostly just causing confusion. It's a one-man project in FB Research, and he hasn't done any namespacing.
