I see, but the problem with that is that it would confuse```www.mydomain.com/welcome``` with ```www.mydomain.com/login?redirect_to=www.mydomain.com/welcome```, or ```/galleries/``` with ```/galleries/324```. maybe I would add a ```^(urlhostregex)?``` that would make that example ```/account``` work as expected (match the path from root), but wouldn't match other things like ```/groups/accounts/321```. 
With the final $, I don't know, I think I would prefer to make users be explicit (adding a final *) than getting accidental matches.
