I don’t think you can understand this inyan with a “hagashah mussari”. This relates to a sog from Rav Hutner, ‘The darshanim said mihr dahr arein legen in die pessukim’, the baalei mussar said, ‘Mihr darf nicht arein leigin, nur mihr darf arus nehmen fun die pessukim.’ Rav Hutner said, it comes out, diese legen arein und diese nemmen arois ober keiner sogt peshat nischt!
(shaygetz – apologies for my german yiddish)
The kevius ha’halacha has got nothing to do with a “ramah nisgavah” of adinus hamidos.
