WRONG_INDENTATION: why are extendedIndentOfParameters, extendedIndentAfterOperators, and extendedIndentBeforeDot set to false?

[0x6675636b796f75676974687562]

As of DiKTat 1.1.1, the default configuration for WRONG_INDENTATION looks like this:

- name: WRONG_INDENTATION
  enabled: true
  configuration:
    newlineAtEnd: true
    extendedIndentOfParameters: false
    alignedParameters: true
    extendedIndentAfterOperators: false
    extendedIndentBeforeDot: false
    indentationSize: 4

i. e. all extendedIndent* flags are set to false now by default. Why so?

All these flags:

• extendedIndentOfParameters,
• extendedIndentAfterOperators, and
• extendedIndentBeforeDot

are in control of whether continuation indent should be enabled or not (in various contexts), while the modern Kotlin style guide doesn't mention any continuation indent at all.

This paragraph (Differences between "Kotlin coding conventions" and "IntelliJ IDEA default code style") describes why the continuation indent is gone from the style guide:

The most notable change is in the continuation indentation policy. There's a nice idea to use the double indent for showing that a multi-line expression hasn't ended on the previous line. This is a very simple and general rule, but several Kotlin constructions look a bit awkward when they are formatted this way. In Kotlin coding conventions, it's recommended to use a single indent in cases where the long continuation indent has been forced before.

What Kotlin style guide for Android prescribes is consistent with the above:

When a function signature does not fit on a single line, break each parameter declaration onto its own line. Parameters defined in this format should use a single indent (+4). The closing parenthesis ()) and return type are placed on their own line with no additional indent.
