Many options are extremely technical, and refer internals, making it difficult to translate usefully. This came up in discussion of e.g. #10949. If a message is not understood by translators (which are typically end-users, not developers) they’ll either translate it literally, making it harder to understand instead of easier, with the added drawback of the user no longer being able to google it.
Also the translation was only working for bitcoin-qt as with the console programs, there is no translation backend. So it was injecting never-used translation messages for bitcoin-cli, -tx.
For these reasons, stop translating options help completely. This should not affect the output in any way * except for bitcoin-qt when a non-English language is configured in the locale.
This implements #10962.
