There is a lot of compelling points raised about this article. Reproducing some parts of it.

The technology is still navigating the early adopter phase, but expectations remain high. “If MABR gets past this phase then it could take off like a rocket,” enthused Jacobs’ principal technologist Tim Constantine, who is very familiar with operation of the MABR technology.

Fluence hopes to crash the others’ party. It formally launched its SUBRE (submerged MABR) product in early 2019, aimed at retrofits and greenfield centralised treatment plants. It hopes its wide reference count in the decentralised sector will help it catch up. “Fluence took a decision over two years ago to focus first on the decentralised market with its MABR,” explained Ilan Wilf, the company’s VP of sales. “This decision is now paying significant dividends. By being focused on a smart packaged plant approach, it provided us with the references to allow us to move onto SUBRE projects.”

Emphasis mine. 2022 has proved that decentralised packages was the right move, now that we have +/-300 plants sold. With China opening up after Covid, fiscal stimulus will hopefully revive some mothballed projects as @jamesc666 mentioned.
