Trying to revert 'the rest' (the switch code generation) while keeping the 
switch op itself seems indeed to be risky and a lot of work compared to just 
turning off the generation. It is not a matter of finding a few commits to 
revert; there are fixes upon fixes, and changes that need to be untangled. It 
does not sound very practical.

Since nobody complained about the actual bug fix, I'm boldly pushing it to 
master.
