Will the Wallet App always remain at https://wallet.steemit.co/ ? The issue I see is that as a user, I am cautious of the domain name being changed on me without me noticing it (a common tactic used by scammers is to create an identical-looking website on a domain name closely resembling the genuine website's domain). So I would be extremely cautious and unnerved if a website redirects me from steemit.com to steemit.co. I would immediately think there is a security compromise and that the steemit.co website is owned by hackers/scammers. If the domain name is sufficiently different, maybe if it includes the word "wallet", then I'd be much more confident that I'm on the official website.

Furthermore, if it's a sufficiently different domain name, could the Wallet App be used by multiple Steem dApps?
