Thanks @o-t-w

@Rumyra @bsmth This is a valid point. I grepped on the preferences and then searched on their values in the source - quite a lot of things are out of date. I'm adding this to a release project so we can start tidying it up. It isn't as simple as fixing this doc - there might be errors in the compatibility data too.

For the list below:

• FALSE - data is correct in doc (feature still experimental)
• TRUE - data is incorrect in doc as this is released. Check BCD. Remove.
• NOTPRESENT - pref not present, so is probably true. But might not be. Check BCD and work out from there.
• NIGHTLY - data should be in expr features, but lets check bcd and that it says nightly

The list:

• [ ] FALSE layout.forms.reveal-password-button.enabled
