is embarrassing enough for the person to say borchu after maariv, telling everyone he was a latecomer. but there’s no need to make it worse, the whole thing takes 10 seconds tops & what damage is he doing to the shul? if anything he is being mikadaish Hashem by causing tons of people to praise Hashem again for what the words mean & help other late comers besides himself make up for being late.
if it would cause people to show up late every day by shmone esrei & tell them i will make it up after davening with borchu, i would understand but this is only done when the person is accidently a minute or 2 late for whatever reason (hard time finding parking or stuck at a traffic light etc….)
