I use Diazo regularly, even today I was doing customisations with Diazo and theme fragments on a client project. It seems the momentum for Plone 6 is towards headless + volto (or something very similar). I'm onboard, with some reservations.
My preferred workflow now is to do all my interactions and design in a Web design tool like Webflow and then use Diazo to "fit" it onto Plone. The signals I'm getting from the community make me feel like my workflow does not fit into the new paradigm. One of the big advantages of Diazo was that it matched this workflow and allowed me to really invest in the best (meaning more visual) theme design tools.
I understand that it's easier to bring people over to the platform if they interface with the tools that they already know (meaning a frontend stack that feels like what they use today).
Unfortunately, rather than supporting design with design tools, the web design tools of today are still what I call "code and peek".
If I'm being fair, Diazo does, in many cases still require code, but when strategically combined with themefragments it really doesn't have the same code and peek feel. It is more of an "assembly" task, a job that happens after the design step. It also means that I get the best of both worlds as my theme can get the full CI/CD treatment.
What I'm trying to ask is... is there a path for a Diazo like experience in the new paradigm?
Don't mind me, just venting a bit.
