At the risk of ruffling feathers (not my intention), I don't see subjunctives in any of the sentences cited here.
For example, in the sentence…
"…even if he had forgotten it, Mrs. Penniman would have remembered it for him"
… the first verb ("had forgotten") is in the past perfect (or pluperfect) tense and the second ("would have remembered") is in the conditional perfect.
Good eye, Rob! I should have said that these examples demonstrate the correct use of the (single) conditional and successfully avoid the "creeping subjunctive" problem. Thanks for the very diplomatic correction. I have updated the post!

Apparently this type of construction is known by English language learners as a "Type III conditional" (for example, see https://langeek.co/en/grammar/course/111/conditional-iii).
But again, not a subjunctive in sight.
