Why YAML LS converts DiagnosticSeverity Warning to Error?

[venmanyarun]

Summary

Relevant information

We are customizing YAML Language server by importing yaml-language-server and noticed that there is code to explicitly convert warning diagnostic severity to error in ValidationHandlers.ts

Is this done due to some client side capability issues or is it just because yaml-language-server has only error diagnostics?

It seems like it was introduced here: #4 with no explanation as to why it was done. This was very early on in the project.

If you look at https://github.com/redhat-developer/yaml-language-server/blob/d3c3ae53a7c5dd0f19d838d42cddebc34a73f59f/src/languageservice/parser/jsonParser07.ts you can see that the diagnostics generated are almost always warnings. Then later on they get converted to errors. Not really sure why.
