Chart immutability implementation missing

This is more like an improvement request then an issue.
Currently on Helm chart section there is no way how to implement an Chart immutability the same way as it is possible for the repositories.

Use Case is following:
Let's say you have an application with Helm chart version 1.4.0 and app Version 1.4.0.
The developer prepares the changes for 1.4.1 but accidently push it without version increase as the version is taken from the package.json to have it exactly mapped.

In this case it will happen that the version 1.4.0 is no longer true and get's overwritten. (I know it does not cause an issue untill helm repo update command is run, but still it is not a safe approach.
