That's a good way to start a fight.
The sort of transformation that happened to British tea, where a brew time was decided on through a collection of scientific-sounding experimental arguments related to extracted tannins and "theine" shaped by commercial market pressures, was only able to happen because changing the brewing style of the tea in this way didn't mess with its "Britishness" for the British, because doing that sort of thing was quite British to begin with.
Gongfu has become a heritage-brewing method, so a lot of the things that make up its essence for some people are not related to the brew parameters. A person who is invested might see boiling it down to the essence as being dismissive of those parts that provide the cultural connection.
I have a hard time thinking of an American tea parallel, other than the way that Anglophiles get annoyed by mentioning things like Teasmades, which tend to get in the way of a good aesthetic. It doesn't really fit, though, because the existence of Teasmades doesn't attack the idea of Anglophile-style British hotel-tea.
The closest parallel I can think of is maybe with Scottish tartans, many of which were invented by the
Sobieski Stuarts as part of a scheme to sell stuff to English tourists. If someone believes that their family tartan is part of their heritage, and they then discover that it was born out of a marketing scheme, well, that can be stressful to adjust to.
So with a fundamental gong fu, a first question to ask is whether spoiling the mystique also spoils the tea. On the one end you have the people who need gongfu to be part of an unbroken and ancient tradition that has survived all the great eras of human history, going back into the earliest past, where history and myth blur together, having tea with the Divine Farmer. For them, spoiling the mystique probably does spoil the tea. In the middle you have the Taiwanese tea-art folks who will willingly admit that a lot of ancient gongfu was invented in Taiwan during the 1970s & 80s, but will do everything they can to banish that behind-the-scenes stuff when the tea is actually being poured. For them, spoiling the mystique makes it easier to spoil the tea. And then in the far end you have the people who are not connected to gongfu tea as a type of experience and are just trying to figure out the mechanism that makes it help certain teas and harm others. For them, spoiling the mystique doesn't do anything to the tea.
