Yes -- hugely underrated. Memory safety vulnerabilities are the cause of 60-70% of exploits [0] including the infamous Heartbleed. Caddy is not susceptible to these types of vulnerabilities. That we continue to deploy C code to the edge -- including software we think is hardened like nginx or Apache or OpenSSL -- boggles my mind.
