Making it default is not really an option as there is overhead involved (a bit more runtime and much larger filesize) that makes no sense when proofing documents and in workflows for print, but enabling is easy with

Thank you! Would it also be possible to have something to the effect of `\setupbackend[format={pdf/ua:2014}` to set up the appropriate options?

I agree that I would prefer to see PDFs given alongside good HTML, but the reality is that this will not happen for some time to come, and in the meantime PDFs remain inaccessible to anyone with a print disability (and inconvenient for the rest of us). If we can improve this situation, it is only right that we do so. If we can in the process encourage wider adoption of ConTeXt, even better.

All best,
