Here's[1] Kenji talking about a "flat-bottomed wok". My Chinese friends cook on a flat bottomed wok and call it a wok. So I'm sorry, but your linguistic rigidity is misplaced.
I’m not saying that large flat bottom frying pans with high edges aren’t useful, I have one and it’s probably my most used pan, it’s just not a complete replacement for a wok.
This is the wok:

It performs one essential function, it needs both a round shape and has to be made of thin sheet steel. You can only have one if you need to place it on a flat induction stove: either it’s thin and flat on the inside, or it’s round on the inside but thick.
you need the round bottom to be able to scoop up the food and churn it. Try using a spatula on a flat bottom "wok" and flip the food to churn it - it doesn't work very well.
There's also an edge between the flat bottom and the round sides. This causes food to get "stuck" there under high heat - leading to burning. A wok is round all the way, so the spatula scrapes everywhere evenly, and you leave no burnt bits.
A flat bottom "wok" is just a pan with high edges.
> Easy tossing for stir fry is just one feature of a wok. For example, the round bottom causes liquids to pool in the center.
The idiom comes for fighting battles with absolutely devastating casualties to capture positions of very low strategic importance. Establishing consensus that woks may only have round bottoms may fulfil the last part, but having people write a few counter-arguments is by no means a devastating loss, it’s just the discussion forum serving its intended purpose.
There is no such thing. A round bottom is a defining feature of a wok. If it doesn’t have a round bottom it isn’t a wok by definition. A round bottom is essential to how a wok is used.
