Bowl Coatings

I dislike them in the extreme because they serve no useful purpose and because someone else decides how I should receive my new pipe. But that is just me. There are arguments for and against. My purpose is not to have this discussion again but to ask what you think about going to the trouble to remove them as compared to leaving them in place, and in particular whether leaving them in place detracts from the smoking quality of the pipe. I know the antis will say that they want nothing between their tobacco and the briar, but it seems to me that this only uninformed opinion.
I've never read anyone saying that I bought X pipe and left the coating in, and I could tell the VAs in X blend, that I've smoked to the tune of 500 tins, don't sing the same. Further I know that that lessening is due to the coating; because in fact when I bought X pipe I also bought another in every respect; and having removed the coating from one, in a side by side comparison, having tested the wood and finding it identical, taking all measurements of every length, width and angle. . .in short, having ruled out all possible variation other than the bowl coating, I can indeed say that it negatively affected the smoke.
However, it also being true that the observer affects the test, I'm not sure if my mood was the same, and to tell you the truth what about those barbeque pork rinds I ate a few hours before one of the smokes? Also I'd had a tobacco diet of heavy latakia for three days before the test, and my mouth was a tad stinky.
That the many anti-coating pipe smokers haven't done this test leaves me with a poverty of informed opinion, and I come to you for yours. Thanks in advance.

Bowl coatings are just that, substances applied to the walls of the chamber by the manufacturer/artisan before it is sold.

That would make sense, but I'm not sure this issue can be regarded in any other way than the maker being in control of the pipe making process; and can choose to coat or not coat. I've heard it said that they coat because they think a dark bowl looks better and will help sell the pipe. I wonder though if it's not insurance against burnout for the maker, really, so that if every pipe they sell is coated, the coating means, to them, that it won't burnout and they will have less bother from customers seeking a refund or some other remedy.
