They do give a reason: mDNS is a standard that was assigned .local. mDNS is useful for a number of reasons. (One of its original codenames was "Bonjour" if that helps connect the dots on how old mDNS is at this point.)

It's not worth the effort to break mDNS because lots of apps can use mDNS, it's a useful standard. In fact, in many LANs today (on modern operating systems inc. relatively recent versions of Windows 10 as Microsoft was one of the last to adopt mDNS) mDNS does almost everything people would want DNS to do in LAN scope anyway and you could get away with not assigning any local DNS and just using mDNS services.
