It was pretty clear to me that the comment was a description of the respective characteristics of glibc and musl in terms of security, while avoiding any conclusion: glibc has heap hardening, which is good for security, but a complex codebase, which is bad for security. Meanwhile, musl is small and understandable, which is good for security, but with a naive codebase that lacks hardening, which is bad for security. Which is better is intentionally left to the reader to avoid flamewars.
