Well, that's the point.  We already have multiple, perfectly functional,
caching resolvers.  We have resolver libraries.  Why did the systemd
project add this to the scope of the project for "a system and service
manager for Linux"?  Why didn't they re-use existing services and/or
libraries?  Why re-invent a wheel that happens to have a number of
corner cases that can be tricky to get right (and a security problem if
you get it wrong)?
