Preserving comments

[Trojaner]

Is it possible to update an existing yaml file while preserving comments at the same time?

We currently need this for OpenMod (OpenMod is a free and open source plugin framework). Sometimes we add new options to the config yamls. These need to be merged to the current user configs but we would like to preserve comments. Currently we use YamlDotNet which can't do this and the authors of it don't appear to be interested into adding this either.

Example use case

1. User installs OpenMod and the following yaml gets created:

rcon:
   # Some long comment that describe what bind does and why it is set like that
   bind: 0.0.0.0
   enabled: true

2. An OpenMod update adds a new "rcon:port" option with 1554 as default value
3. The yaml file gets updated while preserving comments:

rcon:
   # Some long comment that describe what bind does and why it is set like that
   bind: 0.0.0.0
   port: 1554
   enabled: true

Probably not out of the box and likely only by using low level model

Currently we use YamlDotNet which can't do this and the authors of it don't appear to be interested into adding this either.

I'm not against the feature but if you want it, you will have to contribute to it, PR welcome
