Ignoring case for elision step of french analyzer

问题

ElasticSearch Nest seems to be missing the elision articles_case flag as discussed in this question: ArticleCase missing from nest elision filter?

I noticed the official French analyzer has a lowercase filter immediately after the french_elision filter like so:

  "analyzer": {
    "rebuilt_french": {
      "tokenizer":  "standard",
      "filter": [
        "french_elision",  // <==== Has the ignore case property set
        "lowercase",
        "french_stop",
        "french_keywords",
        "french_stemmer"
      ]
    }
  }

Could I placed the lowercase step before the elision one and get the same behavior as if I had the articles_case property set? Or would that result in something different/bad compared to the way the official french analyzer is built?
