This was discussed in the early days of federation and the consensus was that a block should be a hard-block as most likely the offending instance isn’t contributing in a good way on 3rd party communities either.
However it looks like the allow-list is less strict and lets comments from non-allowed instances through if they are on 3rd party communities. But I have not confirmed this myself.
