Unfortunately this case is likely to be more similar to how certain marsupials etc react to the domestic dog, they'll often let them get close because they don't naturally see them as a threat, and once they're close enough speed isn't as big a factor.
If the thylacine focused on wallabies it would be fantastic (as the populations are out of control) but it's the smaller more endangered species I worry for.
All hypotheticals of course, we're at least a decade off a thylacine even being thought about being cloned.
Well, seems to me, before they're released into the wild, I should be able to get a hefty government grant to go squirt thylacine urine throughout Tas forests while kicking quolls and native rodents. Sorted.
