So Hanoi time has always had the same offset same as Bangkok time from 1970-01-01 00:00:00 UTC to the present, and, like Bangkok, has never had summer time/DST?
If so, then is the reason that we have
Link Asia/Bangkok Asia/Phnom_Penh # Cambodia
Link Asia/Bangkok Asia/Vientiane # Laos
but don't have, for example,
Link Asia/Bangkok Asia/Hanoi # (North) Vietnam
that Asia/Phnom_Penh and Asia/Vientiane existed as separate entries before being combined with Asia/Bangkok, so that we need to keep their entire around for backwards compatibility, but there had never been an Asia/Hanoi?
