MDIL is mostly native machine code (e.g. ARM or x64 instructions). Transforming MDIL back to source code would require significant analysis and effort. It would be more like to transforming a compiled C++ application back into C++.
Also, note that end users wouldn't be trying to transform MDIL back to source code. MDIL goes through the 'binding' step that transforms it to native machine code.
