Several Years ago, I read of an effort by a fellow to persuade a maker (Pedersoli, perhaps?) to build their 12 gauge double with flintlocks as well as caplocks. With all the back and forth it became apparent that the manufacturor was far more willing to listen to their so-called "Marketing Experts" than than to the voice of the many customers. The fellow even had an email/ snail mail campaign to going with some success, to demonstrate his point, but all to no avail... :-(
I have found that at some point, a maker chooses to become a corporation, and the next thing you know corporate decsions prevail based on scientific market research, cost analysis, and penny-slicing manufacturing "improvements". At that point, the customer's wants and desires are no longer relevant, and he has become merely the last cog in the "consumer machine".
However, before we lament this situation completely, we can see 3 great benefits: mass production of affordable standardized products; and a New Niche for makers such as TVM and a perfect Niche for the Custom Builders.
check out the discussion on the builder's forum about CaptChee's Marvelous project:

perhaps you could persuade CaptChee to build a flinter for you? ...
