No. To ensure that userland functionality that is based on compiler
internals (token stream, abstract syntax tree, bytecode) does not fall out
of sync with the compiler.

We already have an extension that is built-in and enabled-by-default for
the token stream. Why not have one for the abstract syntax tree and
bytecode representations?
