You're correct, resetBuild is a *very* big hammer, only to be used in 
exceptional circumstances (I can probably count the number of times I've 
used it on one hand).  deleteBuild is also only meant for use by the 
koji-gc script, and should really never be called manually.  That's why 
neither of these methods are exposed via the koji cmd-line.  If you're 
going to use them, think very hard about what you're doing, why you're 
doing it, and proceed with caution.
