Question regarding getaddrinfo (soup-dns.c)

Is there any reasons why getaddrinfo is called with the AI_CANONNAME hint? It does not seem that the ai_cannonname is used any way, and it forces a reverse DNS lookup that it seems is not really needed. When the reverse DNS lookup fails, the call to getaddrinfo is blocked until the timeout/attemps expire.
Would it cause any issue if this hint was removed from subsequent libsoup releases?
Thank you,
