I think the main cause for concern here is not the acidental release of 
(probably) non-viable bacterial spores but the possibility of active human 
intervantion. By this I mean the risk of introducing sequences of ancient 
DNA into modern strains by experimentation and producing a new organism. 
This poses a danger because it bypasses the usal "arms race" between enemies 
and prey. Usually, small evolutionary mutations within bacteria give them an 
advantage over their host which can respond by evolving "counter-measures" 
such as more effective immune responses. If the enemy (bacteria) are given 
what may be a huge advantage by removing the relatively slow evolutionary 
process then they may simply become too effecient too quickly for other 
organism to defend themselves.
