My two most common uses are:

- It has to take up about X pixels on the screen, or
- It has to be exactly N units on the ground

I don't really care about how this is stored in the schema, but if the
UI makes it more difficult for me to perform these tasks, it will reduce
my productivity and increase my frustration level... :)

About being able to set size, etc, based on expressions...  These would
have to be defined at the layer level, wouldn't they?  I mean... if
you're creating a symbol that is only relevant to a fixed feature schema
that's a bit pointless / limiting...

Another thing that may make sense is to change the ScaleX and ScaleY
elements to be absolute sizes (SizeX and SizeY) instead. This would
remove the need to specify a scale (it would be implied), but it would
require one to know the exact bounds of the symbol in order to compute
said scale. This is not always possible since the size of the symbol may
change depending on expressions based on feature attributes. Hence
specifying a scale seems to be a better-defined approach than specifying
a size.
