TL;DR: the many other helpful comments (my apologies), but just letting you know my 2018 Model S originally came with Homelink and as I recall, the Only fault was when I was approaching home and the car sent a signal to activate the garage door, only to find my wife was outside raking leaves and standing quite near the ALREADY OPEN garage, and the door suddenly rolling down startled the heck out of her.
So I'm not sure how the new version is now, but the Homelink unit on my S was able to be set at activation distances from quite far away and I suggest setting your activation signal to go off nearer, like +/-20 feet or otherwise close enough, that you can see the situation around your garage door in time to click it off if need be.
But otherwise, for me at least, Homelink functioned flawlessly and I do miss it.
