It is not, and never has been, a contest between ‘rules’ and mercy.
Frankly, your attempt to make it so–and of course, to come down square footed on the side of “forget the RULES, just be mercy/nice” may help you feel good about yourself, but has nothing to do with the actual post/subject.
It is not, and never has been, required for a person who is not receiving the Eucharist to get in the communion line for a blessing.
It is, and always has been, a reprehensible practice to try to set up ‘rules’ in opposition to ‘love’, as if they are mutually exclusive.
It is, and always has been, a Catholic teaching that obedience is a virtue, and disobedience a sin.
I am not saying that Joe Pewsitter and his 3 year old who go up and ‘ask for a blessing’ are bad, disobedient, should be shunned, scolded etc. That’s what YOU say I say, it is not what I actually say or have said.
I am saying that while Joe Pewsitter and his 3 year old --and the priest (note that the EMHCs cannot give a blessing) may be in compliance with the bishop, or may be sincerely, but erroneously, thinking that this is a good practice, and by ‘good’ I mean they think it is addressing a ‘lack’ (though it does not as Joe and his 3 year old are already going to get a blessing at the end of Mass, that Joe, and the 3 year old, never have, and never will be, required to get a blessing in the communion line if they are unable to receive.
And I’m saying that people who go around and start calling people who simply state the facts are rigid, hateful, unmerciful, etc., etc. are absolutely mistaken.
