Yes I saw the methods, and as for XHR and its headers, I don't find them user friendly enough
The "search" property could stand as is, but I personally think that having a Web Storage like key/value mapping for the parameters would make the code more readable.
We could then have a "params" or "parameters" property with key / value mapping and implementing the Storage interface:
Developers who are more comfortable with methods would then still be happy, and because of having the same interface, the learning curve would be better.

What I would love in the enhancement of parameters management, is that the developer should not need to take care about URL encoding of the names and values any more.... all those encoding/decoding could be done automatically, either with your proposed methods or using a Storage interface...

Going progressively makes sense

I started my purpose saying "Unfortunately...", but in the end, it looks like the Location/URL interface, in combination with the Storage interface should fit with any of the mentioned schemes. The only specificity being the format of the "tel:" parameters (it'd be great if we could update the RFC). I must say I'm more comfortable with the matching of this URL interface with "mailto:", "tel:", "sms:", and "tv:" than with "data:" or "javascript:"

Bellow some potential examples for those schemes using the URL and the Storage interfaces (without showing the methods)

mailto:joe at example.com?cc=bob at example.com&subject=current-issue&body=send%20current-issue%0D%0Asend%20index

        host: "joe at example.com",
        hostname: "joe at example.com",
        href: "joe at example.com?cc=bob at example.com&subject=current-issue&body=send%20current-issue%0D%0Asend%20index",
        parameters: {
                cc: "bob at example.com",
                subject: "current-issue",
                body: "send current-issue\r\nsend index"
        pathname: "",
        port: "",
        protocol: "mailto:",
        search: "?cc=bob at example.com&body=hello",


        host: "+11231231234",
        hostname: "+11231231234",
        href: "+11231231234;isub=8978",
        parameters: {
                isub: "8978"
        pathname: "",
        port: "",
        protocol: "tel:",
        search: ""


        host: "+15105550101",
        hostname: "+15105550101",
        href: "+15105550101?body=hello%20there",
        parameters: {
                body: "hello there"
        pathname: "",
        port: "",
        protocol: "sms:",
        search: ""


        host: "west.hbo.com",
        hostname: "west.hbo.com",
        href: "west.hbo.com",
        parameters: {}
        pathname: "",
        port: "",
        protocol: "tv:",
        search: ""

data:image/png;base64; ........

        host: "",
        hostname: "",
        href: "image/png;base64; ........",
        parameters: {} // might include auto-generated mediaType & charset string parameters and base64 boolean parameter
        pathname: "",
        port: "",
        protocol: "data:",
        search: ""
