+1 for the above. Building a new site for some time now and all from the above has been stripped out or changed from default XC code. Thanks Ryan for your post, although you are not the first one, all this has been said for years by many XC devs or users and yet it still remains.
Since XC5 is following the same model and already coded that way what are the chances QT will completely scrap address book/checkout/register process and re-build it as it should have been done in the first place? We have been asking for this since v.4.4.x.
The problem is - before that there was no address book, it has been asked for millions of time and finally coded in 4.4.x but coded wrong.... Since then even so asked millions of times to get it done right nothing has changed - the address book and checkout gets patched, yes patched, here or there with something and it just makes the code even more bloated and hard to follow or correct...
With every new version XC users/devs hope that this will get fixed.... I keep my hope for many years now
But seeing same in XC5 is a little bit of disappointment...
