The tap for you main water shut off is broken? so you have no way of shutting off the water to your house if you had to? I'd be far more concerned with that issue tbh. If you have to replace the tap entirely, that would mean water would have to be shutoff outside your home, I think that gets pricey as the city needs to do that.

I'd replace it personally. I don't like messing around with plumbing. Kill two birds with one stone. That slow leek could turn into a really fast leak and you have no way of stopping it. That would be a hell of a mess and would be surprised if your insurer covered the resulting water damage.
