The parse is stored in a bytecode format (the same one used when
writing a file with zcompile) so:

It's much smaller than the source (usually), and takes up less memory.

It's much closer to being directly executable than the source, and
therefore faster.

Zach's use case is unusual; there's typically not any reason to "preserve more".
