It's also important to know the differences between alternate universes, alternate timelines and alternate realities. Here, we are talking about alternate/deviant timelines rather than universes, which works in our favour. For some, it's difficult to grasp that difference when you have Bernice Summerfield Unbound being set in "David Warner's Universe". But you have to understand, it's not a parallel universe, rather a deviant timeline, which evidently needs its own version of the DWU.

If you've followed me so far, you'll see that it supports Unbound Adventures being valid. No nitpicking about "well this is one is like this whereas this one has Derek Jacobi in it". They were all made with the same intention in mind - to have a point of divergence from the original DWU timeline and to deviate into its own. This fact alone is why it has to be valid.

On the other hand, if they rewrote the Warner stories and had his background and previous incarnations notably unlike our Hartnell/Troughton incarnations, that would be an alternate universe and would only become valid if it came into touch with the DWU. If tough to understand but eventually it clicks.
