Jothar: Did Reb Dovid specifically pasken that the heter can be used when it is NOT bshas hadchak (appraently differing from Reb Moshe)? Or, perhaps, he held that a specific time/situation/place WAS bshas hadchak, and permitted THEN. And does Reb Dovid (like Reb Moshe) hold the heter should only be used by a non-Baal Nefesh?

What is the mekor for this psak of Reb Dovid?

Josh31: One mitzvah is not exclusive to another. I assume you would not advocate to stop focusing on shatnez so we can better focus on shmiras haloshon. We can do both. Same here.
