Do those rules actually limit UI?

The say how a user agent must parse a value attribute provided in the
source.  And they constrain what a UA may send back to the server.  But
surely a UA can pick any UI they want for this -- including a text box
where the user types a comma, and a decimal point displays as a comma?
