Sure, I just meant it as an example of where factors other than technical superiority have determined the technology chosen.
Thinking about it more, I suppose @TheVat's point may not actually be a technical one really, but more an economic one, viz. why spend limited resources on a "sticking plaster" technology, rather than on those that address the problem at source? But again my view would be the amount of resources is not really fixed. Some governments, corporations/societies may be willing to devote funds and effort to a "sticking plaster" technology that they would not be willing to expend on, say hydrogen, or nuclear energy, in which case I would say let them do that then, at least to see how far it can be made to work, while others pursue the more fundamental solutions.
