      Continuing the conversation on github for the 混ぜ書き form, but I now notice that 丸飲み is not in daijs or sankoku.  Common as it is, it should be discouraged, I think.

Though incidentally, since 呑 is not joyo, that makes 丸のみ the only technically-approved newspaper form, and we've hidden it.

      Encountered in the [sk] form.  The ngrams seem high enough that it's fair to indicate this is a common form, especially when のみ can be parsed in other weird ways if you don't realize this.

Fairly easily explained.  "飲" isn't the ideal kanji, and 呑 is somewhat less common.  When in doubt, hiragana...
