Sure, it has support for queueing, but it's only there to cover the infrequent cases when the destination host is down. In the case of dialup users we are looking at hosts with typical "uptimes" measured in minutes rather than months so the design is stretched a bit :) UUCP on the other hand was designed for batch transfers to hosts that connect at their whim. It wastes far fewer cycles checking to see if a host is available and it doesn't require any kludges (kicking off sendmail -qR) to deliver when the host does answer.
