CC 2017 was offered to everyone with an Adobe ID as a public beta preview. Did you try it? Did you provide feedback? 'Cuz that's where the DW team learned what users want. As you can imagine, there were many different views about which direction it should take. Kind of like an election campaign.
The public beta preview are useless.
Every development team has a leader who takes the decisions for all (not with election campaigns), maybe Dreamweaver's development team not have a good leader...
The big mistake with Dreamweaver (my opinion, obviously) is that it has become in the last years a simple (and expensive) css/html editor.
Dreamweaver was born as server behaviour tools with advanced extensions to allow to develop beyond the limits/skills of the web designer.
Now it's an empty box, only DMXzone and PVII develop useful extensions but nothing that you can easily find ready to use on CMS as WordPress or marketplace ThemeForest/CodeCanyon.
