Confusing "no deprecated lang param usage" in etymology templates?

[digitalheir]

Wiktionary entry for scouse:

{{clipping of|en|lobscouse|dot=,}} of uncertain origin.

Kaikki output:

  "etymology_templates": [
    {
      "args": {
        "1": "Clipping of <span class='form-of-definition-link'><i class=\"Latn mention\" lang=\"en\">lobscouse</i></span>,",
        "lang": ""
      },
      "expansion": "Clipping of lobscouse,",
      "name": "no deprecated lang param usage"
    },
    {
      "args": {
        "1": "en",
        "2": "lobscouse",
        "dot": ","
      },
      "expansion": "Clipping of lobscouse,",
      "name": "clipping of"
    }
  ],

Why does the former exist? "no deprecated lang param usage"? Seems like an internal Wiktionary warning, not very useful to end users I'd say!

Template clipping of uses the no deprecated lang param usage template, the "etymology_templates" field contains all used templates, please see #611 (comment)

A work around was committed in c46cdd8

Is it expected that "no deprecated lang param usage" is in both "ADDITIONAL_EXPAND_TEMPLATES" and ignored_etymology_templates?

[xxyzz]

Probably fine. ADDITIONAL_EXPAND_TEMPLATES pre-expands the template and ignored_etymology_templates removes the template from "etymology_templates" list.
