In my experience, it takes 2 generation of software to get things right.
These days, you are not going to ask a developer to program in assembler
just to get the most optimal memory allocation. 
The complexity of the desktop environments is going to grow constantly,
and this is not a trend one can fight. Same for the underlying
technologies, I don't think the devs see too much the memory
consumption, many of it is hidden in all the frameworks involved.
And often the first generation of a piece of software will focus on
functionality and stability, and it takes another generation to profile
and optimize.
