So is it a good thing, or is it bad? Does it make 'Love' less a public thing in any way?
I would not say good or bad but a very human thing.
And as a side note, love does not have to be public. When pandemic restrictions no longer apply, going into a public restroom and cleaning it up for the next person to use it, for example, could be a love in action act that will never be public.
In these pandemic times, I've seen "thank you" signs that were put up by someone unknown expressing the sentiment that we honor those who are at particular risk for COVID-19. These are anonymous acts of love.
