It would be empowering for the user to be able to steer which file format definitions are developed or updated by having a crowd sourcing platform. If a user suggests the development or update of a file format definition, SDL could estimate the cost (outsource the coding?) and open a crowd-funding project. Then every user who is interested could donate to the cause. Of course, there would have to be transparency as to how much has been donated, how much is needed and then a commitment by SDL, say, to make the file format available within 1 month of reaching the required funding.
We are a community of users, so we might as well team up to help develop what we need.
