> There’s a cheap ($20?) add on for our water heater that adds a conductivity sensor in the drip pan, and a shutoff valve on the inlet.
Oh I know, they are awesome. They should come standard, and more people should know about them. It is one of those things I try to bring up in conversations at random, because holy crap the # of people I know who have had water damage from their water heating dramatically failing is too high. Heck it happened to my family twice while I was growing up.

Why not? I've seen places where with a drip pan angled towards a hole connects to a pipe that drains outside.
It should work for slow leaks. Doesn't do anything if the tank bursts of course...

The drip pan is for slow leaks , not for flushing or a gusher - but most gushers start as slow leaks, and it’s easy for a drip to cause massive damage if it goes unnoticed for months.

What’s the name of this 20 dollar device?!

Just a water tank moisture detector, e.g. https://a.co/0ujkOuD
There’s a slightly more expensive variant from another company that supposedly looks at flow for the whole house, and cuts water off due to slow leaks or burst pipes.
I’m shocked that the water heater cutoff valve isn’t required by code. In contrast, plumbed drain lines for water tank flushing have a much worse payoff per dollar and are required by code around here. (When I’m feeling cynical, I assume that the codes here are designed to subsidize contractors while maximally screwing over home owners.)
Edit: the plumbed lines don’t actually help with leaks; so they do nothing that a garden hose would not accomplish.
