By that logic, you should get rid of about everything in standard libraries. A simple RNG? Anything related to floating point? Multi-threading? Character encodings? Unicode normalization? Time and date handling? All fraught with danger for those who do not know, and "basically a semester course and well out of scope for standard library docs".

Surely, it would be better to supply good implementations of algorithms rather than refrain from doing that, and letting programmers write and use bad ones instead?

IMO, the discussion should be about what c/should end up in the _standard_ library, and what is better put in a separate product/download.
