Because they should behave identically to other forms of quoting that bash

$'' is left as-is inside double quotes, why should it treated

Yes, I thought of that.

Except it's not unconditional. You have to accommodate ${x#$'value'} in
the here-document expansion path because "${x#$'value'}" is processed for
escape sequences. You're right that it should not be treated differently,
but it's not as simple as leaving $'...' and $"..." unmodified.
