Aiming for no regressions is a worthy aim, but I believe unachieveable
in a project of any size.  For sure it's impossible if there is ever a
need to make large-scale infrastructural changes, which inevitably is
occasionally the case if the project is to live a long time.

For example, if the dyngen/gcc-based backend is replaced by a
self-contained handwritten one, I would be amazed if there were not
a few obscure regressions whilst the new backend is brought up to the 
same level of stability as the current one.  At least, that is what
I know from my own code generator hacking.
