Functionally in the sense of “if you look at it long and hard enough you will find all the information you want in there”, yes.
Functionally in the sense that a lightweight time line provides just the information I require in just the way I can process it quickly and non ambiguously, then no. It’s not equivalent.
This feature request and your sketch is quite related to what I asked for ages ago:
I’d appreciate if at the very least there was a small but noticeable vertical gap in between dates (@dreev also suggested this). Making everything you grouped together with curly braces into a visually separate block of goals. I want more though 
Even with that there is still a lot of information that you don’t need in a lot of situations, such as the graphs (pretty as they might be). This just adds noise and distraction. I know tables are easy to program 
I need spatial clues though.
I also second that the colours are next to useless when you have deadlines prior to 24:00 and so on. You will have BIG RED GOALS in your face the entire day and need to convince yourself that red = OK because there is nothing you can do about it.
