James Hoffman (coffee professional, winner of WBC) discusses the obscurity of single dose baskets in his video here. He mentions they're not often used in the home because he is discussing home espresso but the 50 caveats of single dose baskets apply to the industry too.

Discussion of single baskets by The Wired Gourmet pointing out that in the industry double and triple baskets are used and split in vast preference to single shot baskets. Also covering the difficulty of working with single shot baskets:

The reason people in this section are disagreeing with me is because they have never made specialty espresso and have no idea how difficult it is to dial in a single basket, even if you're a cafe.
“All espresso based drinks” seems incredibly broad.
There may be some niche drinks that use less espresso liquid, but they're not common. If I was only given 0.8 fl oz (which, is what a single shot looks like) in an espresso drink I would be upset.
For reference, I use a 36g shot (basically 36ml if you wait for the crema to dissipate) for a 170ml "flat white" at home. This achieves a balanced strength for this kind of drink. You really have to get into the tiny drink category before you really reach the realm of "this is too strong and I must use a split single". And, in those cases, due to the fact of the double shot (and, I would struggle to come up with "sources" but it's again generally accepted that unless you can use the second split shot for a drink immediately, it goes down the sink), you are still often using a double worth of coffee for a single shot drink.
