Yeah.  Honestly, putting generated code in the tarballs and making the
build system deal with both the tarball/non-tarball case has always
seemed like a pain.  I'd almost rather just see it be consistent...

It does avoid having to install bison and flex.  (It doesn't avoid
python 2.x.)  Developers have them already, and they're pretty common.
For most distros, it's probably just a matter of flagging the build
dependency in the package description and pointing tools at it.  Is this
really useful for anybody?

If it is, then sure, it's totally solvable.  If it's not, well...
