I’m not happy about LinearAlgebra. I’m not really happy about Random either but I realize that my belief that Random should be included by default is a result of my specific educational background. The others I think are fair. (I’ve used a lot of special functions in my life, but even I don’t see them as “default” functionality, no pun intended.)
Note however that you still have an awful lot of LinearAlgebra functionality out of the box, since you have all operators (e.g. remember you can also take the adjoint with A' and inner products with dots). Were that not the case I’m sure many of us would have complained very loudly.
