一昨日の「#4945. なぜ推奨を表わす動詞の that 節中で shall？」 ([2022-11-10-1]) および昨日の「#4946. 推奨を表わす動詞の that 節中における shall の歴史的用例」 ([2022-11-11-1]) の記事に引き続き，従属節内で接続法（仮定法）現在でもなく should でもなく，意外な shall が用いられている歴史的用例を歴史的辞書からもっと集めてみました．
OED を調べると，問題の用法は shall, v. の語義11aに相当します．
11. In clauses expressing the purposed result of some action, or the object of a desire, intention, command, or request. (Often admitting of being replaced by may; in Old English, and occasionally as late as the 17th cent., the present subjunctive was used as in Latin.)
a. in clause of purpose usually introduced by that.
In this use modern idiom prefers should (22a): see quot. 1611 below, and the appended remarks.

とりわけ1829年と1847年の例は，推奨を表わす今回の問題の用法に近似します．
MED の shulen v.(1) の語義4a(b)と21b(ab)辺りにも，完全にピッタリの例ではないにせよ類例が挙げられています．
歴史的な観点からすると，推奨を表わす動詞の that 節中における shall の用法の「源泉」は，緩く中英語まではたどれるといえそうです．これを受けて，改めて「物議を醸す日本ハム新球場「ファウルゾーンの広さ」問題を考えていただければと思います．
この3日間の hellog 記事のまとめとして，今朝の Voicy 「英語の語源が身につくラジオ (heldio)」で「#530. 日本ハム新球場問題の背後にある英語版公認野球規則の shall の用法について」を取り上げました．そちらもぜひお聴きください．
