copy-paste effect over the previous

Something that has been bothering me for a while.

Pr 2017.1

in After Effects when I copy-paste an effect from one layer to another, and it's the same type of effect, it "runs over" the effect and replace it. this is instead of creating another instance of the same effect.

in Premiere I see it does not work this way and it adds another instance. what happens if you apply the same effect for a few clips (could be a good number of those) and then decide to change the effect? so you change one time on one clip, COPY... and? the process I have found is selecting the clips before I hit paste, and choose "remove attributes" then unchecking the effects I want to keep, click o.k. this will remove the previous instance of the effect, and then finally PASTE.

I am asking especially those of you who are well experienced inside this software: wouldn't a copy-paste function that would replace the effect make more sense and a more efficient way to work? if I wanted another instance, I would copy two instances from the start and not one. I know about applying an effect on a Master Clip and that's great, but there could be a case where the same effect is applied on clips that are not from the same source... more importantly, I don't see a case where I would copy-paste an effect to another layer and want two of those instead of one.

What do you think?
