Yes, you can make your own personal ones.i have made my addons for auto research and auto making items for research (traits) for my toons, so yes - it is possible.
Not sharing them is actually the default. When you create an addon it will only exist on your computer, you have to upload it to a fan site (or more than one) before anyone else can get it, and you'll probably have to post about it on forums and things as well since not many people are going to download a random addon they've never heard of just to see what it does.
But addons in this game are much more limited than in most. You can't make new objects for the game or modify skills, stats etc. or change what characters are able to do. You're pretty much limited to changing the UI, and everyone else making addons will have exactly the same capabilities.
So for example you could make an addon which makes combat easier by warning you when a major attack is coming and you'll need to block, but anyone else capable of making addons can do that too and probably already has - so anyone else can get the same ability. You couldn't make a secret addon which will automatically block when it detects a major attack coming.

But somebody can make an addon for incoming dmg notification like in pve but only for pvp.
maybe also an addon that will use a specific potion when low in health or in resource.
an addon that tells if the player is CC immune or not, if he's under a potion or not....
I think addon should validated and shared by/with ESO community, otherwise there will always be exploits.
