Just learning that there is an ERC-223 standard that improves on ERC-20. But so far, I haven't seen a contract implementing ERC-223. Is there a reason why smart contract developers still stick with ERC-20? 

Casting here because i can't cast in /ethereum or /evm

Oh wow! Thanks for taking time to explain. So the main thing holding it back is transferability. Makes sense.

ERC20 defines an interface, which is the bare minimum to be found, indexed, traded as a fungible token. 223 defines a behavior which could drastically limit the transferrability of your token. Token developers usually want to have the most liquid assets. 
For the transfer safety, OZ has a "SafeERC20" impl. Also, there's a debate whether it's a good idea to check if an address is a smart contract (there's no way to know if it will be a SC in the future).
Also, I don't understand the reasoning behind the gas cost saving in this ERC.

It might be due to comparability with all the other protocols and infra. Unless it’s directly backwards compatible with ERC-20 it’s likely not gonna take off; way too much money already put into the existing standard
