Hi@dmarkham

While digging in the previous PR of the project I noticed that you had madesome work on BSON support back in 2019 but did not finish it.

If I was to open a PR to make a-bson flag again would you be willing to merge it ?
I understood that you did not like the fact that the generated code would be tied to the external mongodb package but I don't think there is any alternative way to implement a BSON marshaller for now.
