A Java-like language went through this kind of change a few years ago and was extremely well received by its users. I understand your philosophical position, but it isn't supported by the evidence.

I have to disagree with my esteemed colleague John on this one. I believe
that every language has certain characteristics that make it what it is, and
that these things simply shouldn't be changed. I believe that one such
attribute of Java is that all declared entities have an explicit declared
type. I believe it would do great harm to the language to change this.
