This type of thinking is supported by official developer commentary on the Worgen.
"
Worgen are not technically a race and thus cannot reproduce like one. The worgen curse is just a curse. Its origins are rooted in the druidic pack form that was later altered by the Scythe of Elune. The end result is worgen we see today, beings that can transmit their affliction to others via a single bite.
In theory, if two worgen were to mate and produce an offspring, that offspring would not be a worgen. The child would merely possess the genetic material of his or her parents, like any other child sans the curse.[17]"

The answer comes from an Ask CDev Round 4.
So a child of two Worgen cursed parents would come out as a regular human kid.
This is why it's mere gameplay distinction that when we "select a race" in the character creation, that's just to simplify for ease of game use to say, "hey you're picking a Worgen" instead of going "yeah this is a human too, but it's a
Gilnean Human that's been cursed".
What is much more succinct? [Cursed Gilnean Humans] or [Worgen]. Rhetorical question btw.
This game is made up of playing many types of fantasies, if you want to play as a regular joe-schmo human, you pick [Human], if you want to play as a cursed human you pick [Worgen], if you want to play as a dead human you pick [Undead], if you want to play a big burly/thicc human you pick [Kul Tiran].
They are all humans, just different kinds of fantasy. That's why it continues to be silly when people say if you want to play a High Elf, just play a Blood Elf. The fantasy of a Blood Elf is not the fantasy of a High Elf.
High Elves didn't enslave a Naaru, feed on creatures, utilize fel magic, stay haughty/pompous, form the Blood Knights, utilize Blood Magic, display elven superiority, join the Horde. This is all Blood Elf fantasy.
High Elves fed on arcane objects, or dealt with their magical withdrawal through sheer will, they're not haughty/pompous at all and humble themselves with their allies, stayed within the Alliance despite their nation seceding. I mean in essence, these guys are the "joe-schmoe humans" of Elves. They're the base Eevee before any evolution. This is the High Elf fantasy being requested.
High Elves also didn't join the Horde, accept the Blood Elf name, not like the Horde, delve into void magic, get cast out by for their void studies, get almost turned into an ethereal and churned out into a Void being, dealing with maddening whispers (apparently), and re-join the Alliance. This is Void Elf fantasy.
