[Inkscape-devel] "plain svg" is 1.2 not 1.0

saving as plain svg creates an svg document that claims to be svg 1.0 and yet contains things like flowRoot and flowRegion from 1.2

Is there any way to flatten an inkscape document to plain valid svg 1.1? Its a bit inconvenient to have to use "convert to text" on each text flow in the document
