Yeah, displayValue sounds better.

IMO, the IDL attribute should work only with input types of which value
mode is "value". Value mode of input[type=file] is "filename", so empty
string should be returned.

Yes, I'd like to enable selection API for at least type=email and
type=number. All of their existing implementations are text fields. I
haven't seen a request to suport selection API for type=email, etc..
However lack of selection API looks a defect to me.

It doesn't work for type=email.
Suppose an email field has "root@グーグル.com" as a display value. A screen
reader reads it as "root at xn--qcka1pmc.com" because HTMLInputElement::value
returns a sanitized string.
