First of all, thank you so much for taking the time to reply - really much 
appreciated, all the more given how busy I see you are, with so many 
awesome improvements.
I love this "raw beamer" attribute, might make my document a lot more 
readable, yet to try it for other purposes.
Unfortunately, this suggested solution does not help the issue at stake.

The issue is for the content not to get forced slapped onto a slide.
To create a new title page, I need the following piece of code:
\mode<presentation>
  {
    \title[\CourseName{} Lecture 1]{\CourseName{} \newline \, Lecture 1}
    \date{\DayOne{}\Yr{}}
  }
  ###
  \titlepage

And this {...} code cannot sit inside a frame or a latex error is thrown (! 
Illegal parameter number in definition of \iterate.).
After 2.7 - there is no more option for me to write content outside a frame 
- everything is forced into a frame.
"raw beamer" attribute does not escape this behavior unfortunately.

Hence my suggestion last night - i don't know if that would be acceptable 
or even useful?
But i have been thinking that I am perfectly fine with level -2 content not 
being forced onto slides.
From what I read, it looks like reveal.js users only need level -1 content 
slapped onto slides?
Of course, I'd be happy with any other solution you think is best.

Many thank
thomas
