Well, sure the advantage of not solving only for TripleO is that some
time can presumably be spent working on helping to improve Mistral instead
of writing a new API completely from scratch. In general this is a good
thing, and to be encouraged, right? :)
You've mentioned that bug before, have you seen this?
I'm not sure it's even a bug, it's not confirmed as such and it sounds like
the configuration issues mentioned in that thread to me.
But, sure, there will be bugs, are you suggesting we'll have less if we
start from scratch with a TripleO specific API? Be interested to
understand your reasoning if so :)
