Common settings between profiles

[Indeedornot]

In February an update adding Profiles has come. However as of now each profile has their separate settings, meaning you have to set all of the settings and sync common settings between them manually.

For example if you want to share settings between all profiles you'd have to do it by hand each time you change something

I propose that there be some sort of common settings files and in profile settings files we would be able to either
extend it as a whole and have an option to overwrite some settings in full or add to them,
extend it for one setting only (coppy only one setting)

so for example

group1.settings.json
{
  "files.autoSave": "afterDelay"
}

profile1.settings.json
{
  "extends": "group1.settings.json" //path, or array of paths
}
