Yea, i definitely agree with this author more than the last. Also, as both a writer of apps and libraries, i agree libraries pose more opportunity to drag yourself deeply into generic relationships and hyper optimizations.

Strangely i haven't had many of the issues that the previous poster was discussing, though. My issues are usually trying to work around the lack of GATs, lack of trait aliasing, etc. But i use `async_trait` so maybe i'm sidestepping many of the issues from the previous post. /shrug
