Are the final events of DBZ considered canon?


In _Dragon Ball Z_ , the series flashes forward 10 years after the defeat of
Buu and we're introduced to things like Gohan and Videl's daughter Pan, lazy
teenage versions of Trunks and Goten, and a reincarnated Buu (Uub).

Since _Dragon Ball Super_ begins sometime shortly after the defeat of Buu, are
the flash-forward events of _DBZ_ wiped from canon, similar to the _GT_
history?

My biggest point of confusion is the fact that Pan is 4 in the final events of
_DBZ_ , which means she was born 6 years after Goku kills Buu. But at the
beginning of _Dragon Ball Super_ , Gohan and Videl announce they're pregnant
with Pan. This could be explained easily if _Super_ picked up some 5 years
after Buu's defeat, but Goten and Trunks appear to be the same age as they
were in _Z_. So it seems likely that Pan was born way earlier than 6 years
after Buu's defeat.

Do these events reconcile or was the end of _Z_ undone to make room for
_Super_ to tell new stories?




In _Dragon Ball Super_ , Dende makes a mention to Uub and he tells Goku it
would be good if he trains him. That's meant to connect _Dragon Ball Super_
with the end of _Dragon Ball Z_.

As for Trunks and Goten appearance, in _Dragon Ball_ , 4 years have passed
between Goku meeting Bulma and killing King Piccolo, and his appearance (which
is almost identical to Goten by the way) doesn't change. So yes, the final
events of _Dragon Ball Z_ are canon.
