And BTW: I'm astonished to read that a scripting language is "high-level" 
in 
opposit to C/C++. I always thought that the opposit is true: The 
"high-level" languages were C and alike.

They are more perfomant because they have their core files as binary code, 
not as scripts. Scripts are used for fine-tuning.
But these are yesterday's decissions. The question is whether other apps 
should follow Orca's way? Why change useful and working approaches?

Absolutely. Note that the use of SD in Orca is only one of the various 
possibilities SD provides. And, after having solved the sound mixing 
problem for Gnome-Speech by using Pulseaudio, one of the advantages of SD 
with Orca has gone.
