ditabase

https://www.oxygenxml.com/dita/styleguide/webhelp-feedback/Artefact/Topics_and_Information_Types/c_Using_Ditabase.html Can we get rid of <dita> for DITA 2.0.
We just had another issue here and with Oxygen posting the above we are wondering how long the ecology of tools will continue support for <dita>.
I realize this was discussed a few weeks back and it seemed there was support for <dita> removal.
What would be the easiest upgrade for people with <dita> files?
There was some mention of needing a title but users could have an empty title or descriptive title at their option.
