From what I can tell in TZ data, the time zones only diverged between Asia/Baku and Asia/Yerevan in 1992. Considering that the Republic of Artsakh declared independence in 1991, there is a chance that it has followed Armenian (Asia/Yerevan) rules since it declared independence, and thus there is no need for Asia/Stepanakert. However, this is just a guess, and we need more research before deciding whether there is a need to create the zone.

Nagorno-Karabakh is an 'Armenian enclave' inside Azerbaijan, which seceded from Azerbaijan in the 1990s, and has some kind of unclear status of autonomy since a ceasefire agreement in 1994.

Azerbaijan and Armenia have different time zone rules, represented in TZ by Asia/Baku and Asia/Yerevan.
Has anyone researched the time zone and DST rules in Nagorno-Karabakh?
If the time zone rules followed locally differ from Azerbaijan, the situation there justifies the creation of a separate TZ zone. The zone exists now since 25 years with rather high political stability.
