IMHO, this is typical example of a tag that shouldn't have existed until
bullseye was stable.  Having -Wl,--as-needed specified in d/rules AND as
internal default from ld brings no downsides whatsoever, bearing one
"extra" line in d/rules.
Instead, I can see how many man-minutes and precious brain cycles were
lost in bugs like this, since you are not the first person to raise this
question.

I recommend you just either simply ignore the tag for those packages, or
please an override if it bothers you.
No need to overcomplicate a simple matter by removing and-readding flags
when they can simply just stay there.
