I've post a closing answer to this thread. Summary here:
1) no more ask for switch to Hanoi in tzdata ;
2) no more ask for Hanoi link in tzdata ;
3) confirmed the necessity to switch from "Saigon" to "Ho_Chi_Minh".
It seems that 3) is being considered by tzdata maintainers, so we'll probably close this bug soon.
As for 1) and 2) I've understood tzdata is not the right place to do this kind of change so I'll suggest another way: propose multiple city names for time zones at the user interface level, as we can see in some other systems.
Or may be simply don't change anything and explain people what is the time zone naming simple and only rule: the most populous city, and not the capitol as we usually guess it should be...
Anyway, I also understand that this change is not Ubuntu specific and so I'll eventually continue this work at the source in the Debian bug report (linked at top of this page).
Thanks to everybody having participated in this, especially Martin Pitt for the first step with upstream.
FYI...
