My perspective would be absence of submit button (with either
visibility:hidden OR display:none) would give user to create more enhanced
pages that will allow implicit submission like just username & password hit
enter and done and not having mandatory for Sign In button. (just a use
case)

Yes, this reminds me more use case for tablets/mobiles where use need to
scroll the page and click on the Submit button instead he can just use the
Go button on the input may be.

Just to add more analysis
Opera - Does Implicit submission in following cases -
* One text field
* One text field with one visible submit button
* One text field with one display:none submit button
* Two text fields with one visible submit button
* Two text fields with one visibility:hidden submit button
* Two text fields with one display:none submit button

Only in following case it does not -
* Two text fields

Just to consider market shares of browsers - Increasing share of Firefox
(more than 40%) and decreasing share of IE (less than 25%) & also for
Mobiles & Tablets there is Opera Mini which is increasing.
