"Open and Fill" scrolls to the bottom of the page in Chrome

So I have a few reasons I prefer to keep it listed at the home page. But if any of these aren't things to worry about, please do let me know:

1. Quite a few sites don't have a dedicated login page, and instead have an in-page drop down or popup to login from anywhere. If a specific page is listed on such a site, will it still allow me to login on other pages? And if that's where I initially saved it from, it might be some random product page I happened to be on that time.
2. Site paths change over time. While domains can change, that's less common. But a redesign of a site could easily change that deep link into the login page. So I'd end up getting a 404 when I first load the page, and then after manually going back to the home page, would it even fill it on the new page if the deeper link is what was saved?
3. At least with lastpass, I'd sometimes use a listing as a sort of alternative to having all of those same sites bookmarked in the browser. So I'd just type a few letters in and pick it to launch it. In such cases, I might already have a saved login, or I might not even care if I'm logged in or not. I may just want to go to the home page.
4. I came over from LastPass, where I didn't typically store the deep links and that worked fine. So to switch to deep links, I'd have to go through all of my sites and update them.
5. And finally yes, it does look a bit cleaner, but that's less important than the items above.
   

Hope that helps! I'll also give you some other examples of sites that are doing the auto-fill of the email signup. I've also found some where the ?randomstring=otherrandomstring querystring it adds seems to cause some oddities beyond the scrolling, though I don't remember which those were and that was more subtle. I'll give you examples of that if I can find them.
