What happened to escrow transactions?

https://steemit.com/sip/@dan/escrow-sip-steem-improvement-proposal 

Steem escrow transactions would facilitate: 

* crypto-fiat exchange similar to that of [localbitcoins.com](https://localbitcoins.com/?ch=b6o8)
* trade of real world goods and services similar to that of OpenBazaar 
* lending with Steem as collateral that could be powered up and delegated back to the borrower 

SBD would provide a lot of convenience for pricing. 

The exchange, trade and lending would all happen using only fiat and the Steem blockchain and thus bypass Bitcoin as a gateway cryptocurrency. 

This should increase the number of active Steem users, which in turn should increase the value and price of Steem. 

I may be wrong but if the Steem blockchain supports escrow transactions, why not add the feature to User Interfaces such as Steemit.com and see what happens.
