If you look at the training of top riders this is the value they will be monitoring for most of the year, since they know the threshold they need to reach in order to have a realistic chance of achieving a goal.
By all means supplement goals related to an absolute measure like W/kg with those like setting a PB for a TT or moving up a racing category. This will help with motivation and encourage you to consider broader aspects of the sport like aerodynamics, race tactics and the like which make it more interesting. But even with these knowing your w/kg provides a big benefit since it will help you understand what is and is not working to improve them.
The professionals main aim is not achieving a particular threashold though, and they're not paid for that... it's one (of alot of elements that) enable them to compete at that particular level - to ride (and win) the TDF, TT and all that jazz. For them it's just a means to an end, not an abstract end in itself. I'm sure the OP has his own goals in mind, but being in his position I would need something more substantial than the VO2 alone, which he didn't mention so I was wondering what they were.
