It's nice that a government pushes for open standards, and if it gets widely used, maybe it will somehow help development.
But in the meantime, there is still no decent writing tool for our current needs.
When I need to write something, it usually doesn't need to be printed on A4 (or Letter) paper. It is to be viewed on some digital display. And it does't need to be pixel-precise. Just well structured to be understandable. So the natural format would be HTML with CSS, which has become a universal format that can be displayed on anything, and can even be searched as plain text with grep and the like when needed.
But there is no word processing program that produces sane HTML/CSS. The real word processing programs which have all the features and tools to help for writing produce totally insane HTML. The HTML tools are designed for programmers or "web designers" (whatever that really is these days), not for plain writing of content. In the end, I often just send an HTML email done in Thunderbird, or I use Amaya, and mostly a plain text editor with a browser window to re-read it. The alternative is to write in MS Word or Libre/OpenOffice, and produce a f*ing PDF.
I have been longing for a modern "Ami Pro for HTML/CSS" for the last 15 years...
