Does this consume valuable and irreplaceable resources? It will have some cost to implement, but nothing that would preclude later reversal.
Can you identify a set of stopping rules? Missed recruiting targets, degraded morale, reduced unit cohesion. There are objective and subjective metrics that could trigger a reversal if the facts don’t match the hypothesized benefits.
These answers suggest the change might be a two-way door, but what about: Is there near certainty people won’t be harmed? Most certainly not. In fact, it’s obvious the proposal will be scary and disruptive to a number of Vulcans as well as their friends, family, and colleagues. At the very least there’s enough potential for harm to justify more than a two-tweet cost-benefit analysis.
