Yes, apart from advertising the capability I don't imagine it's useful to
produce that dump without a special flag.

I think I can understand people writing a parser when it's sufficient; it won't
need to be recompiled for a specific compiler version (with headers from that
compiler), won't crash the compiler if you did something wrong.  For people more
familiar with a dynamic language like Python than C/C++ it may be just more
comfortable to do it that way.
