Is that realistic? On the clang side there was some discussion about
adding a clean command line interface, but the added value of doing so
seemed small.

However, the challenge then becomes "why would anyone use the 'nice'
one"?  It is likely to get less development and features, and users of
the compiler don't care about academic purity of the implementation
details.  Any features of the 'nice' driver would also need to
supported by the 'ugly' driver also, so I don't see that introducing a
new driver is really all that useful.
