It does not necessarily mean a lack of trust. It could be different incentives or priorities.

For example, some users might desire major redesigns of past work but not bear the cost of the rework. As such, they might perceive some small improvement without any (direct) cost.

Personally, I think some groups have moved so far in the direction of community involvement that they forget the practical implications of diversity. Leadership is hard for many reasons — one big reason is that leading sometimes means making some people unhappy. Still, this is much better than inaction.

Could you please give some examples? I think I follow Rust pretty well, but have no idea what/which-improvements/who/which-groups you could mean.

I don't want to name any particular people or groups, because everyone makes mistakes and has limitations.

I will say this: in my personal experience, I've been a part of groups that struggle in dealing with complex decisions. Many times they get bogged down when they don't find a clear answer that satisfies everyone or all criteria. In many cases, such groups don't have a clear leader or the leader lacks the skills, experience, and character to do what is necessary; namely, choose (and communicate) the least-worst decision that keeps the ball moving forward.

In such cases, it is not necessary (and unrealistic to expect) that everyone agree with every aspect of every decision. A leader needs confidence and persistence to make tough decisions, as opposed to abdicating leadership. Some examples of the latter include (1) ignoring a choice until some default decision is made implicitly or (2) simply choosing the idea from the most vocal person.

Put more broadly, in this context, leaders must balance four aspects: (a) scoping and framing a decision; (b) gathering diverse points of view; (c) building some degree of consensus or buy-in; and (d) making a decision. It appears to me that the Rust language team handled all four comprehensively.
