It's a din derabbanan to preserve a minhag caused by the frequency of a
safeiq. Therefore, even when it's not a safeiq, /some/ of the dinim are
designed to require actions like those caused by the commemorated safeiq.

OTOH, they couldn't legislate a weakening of the original deOraisa,
because it's a taqanah, not a gezeira, nor is it besheiv ve'al ta'aseh.

Why? We make berakhos on dinim derabbanan, and Ashk make berakhos on
minhagim.

This is only a problem in your hypothetical situation that we were still
in actual safeiq, and I thought you agreed it couldn't be reality.

Tir'u baTov!
