I've never once pulled in a new dependency and had the program fail to compile just by virtue of that dependency being present [because both my code and the new code both impl'd the same trait on the same type in some other code]. Because that can't happen because of coherence. (Right?) It's so easy to forget about the problems we don't have because of the (good)
choices people have made in the past. |

yes
Through you still can run into it when unsafe is involved, e.g. C FFI/no_mange or ASM with non-mangled labels as they are globally unique. Through IMHO, it's not a common problem and has ways to make it very unlikely for the projects where it matters.
In the end if you pull in C-FFI code (or provide it) you do ope yourself up to C ABI specific problems.
