Yes, this makes perfect sense.

These are both reasonable ideas.

Imagine being able to bind properties to executables.  I think this
might be easy to do for many systems.  They could all live in a
special section of the executable in order to make it easy to add and
remove them with something like objcopy.  It's easy to imagine a
wrapper around objcopy for manipulating properties like initial heap
size, default classpath, default character encodings, and such.
