It works fine. I tried to find a alternative, but I wasn't lucky.
When I resee your filter, I remember about the multiple parameters in
filter operator with commas (from last version, 5.1.23). And we can add a
second filter run that it applies your filter to result of first run. Then
you can rewrite your filter something like this (in filtering transclusion)
{{{ [tag[Tag 1]*,*[Tag 2],[Tag 3],[Tag 4]]
:filter[tags[]count[]compare:eq[4]] }}}
Although maybe it be less understandble for you.
