Because the .pyc file does not store enough information for an easy
bytecode->AST transformation.  You would need to read from the source code
and and reconstruct the AST.

This is why, as of now, you need to go through compile() to get an AST.  I
personally would rather wait to see how much the AST is actually used before
trying to give it an attribute on code objects.
