This is all growing out of proportion, this whole issue can be resolved
by just thinking logically.
If passwords are being stored in the dictionary then that is a security
issue with the UA and not HTML etc.
If a dictionary stores user words without asking the user first or the
user specifically stores it then that is a implementation issue of the
Password fields should never have spell-checking enabled (not just for
security reasons but because the dictionary might mess up the password
you are typing causing a failed login)

Forms and content fields can have hinting, where they desire spell
checking to be used (commentary fields on websites, article content
fields etc), but it is up to the browser/user/OS settings if it'll
auto-enable checking on those fields.
And currently this is mostly how browsers do this (some better or worse
than others though).
Some CSS enhancements to possibly match the dictionary GUI to the site's
look could be interesting though, but CSS stuff is another group than
Only thing I see to miss in what is mentioned here is sitebased custom
that is something that could be and should be specced. For example, you
might want to use the same base dictionary (original or user extended),
but a different site/sub dictionary depending on if you are writing
