SYS/READ-DECODE can read extension module from url!, but LOAD-EXTENSION will fail

For an extension module, SYS/READ-DECODE calls LOAD-EXTENSION, but that function does not accept a url! source

sys/read-decode: make function! [[
    {Reads code/data from source or DLL, decodes it, returns result
     (binary, block, image,...).}
    source [file! url!] "Source or block of sources?"
    type [word! none!] "File type, or NONE for binary raw data"
    /local data
][
    either type = 'extension [
        data: load-extension source
    ] [
        data: read source
        if find system/options/file-types type
               [data: decode type :data]
    ]
    data
]]
load-extension: make native! [[
    "Low level extension module loader (for DLLs)."
    name [file! binary!] "DLL file or UTF-8 source"
    /dispatch {Specify native command dispatch (from hosted extensions)}
    function [handle!] "Command dispatcher (native)"
]]

In order to make that work, we'd need to download the URL to a cache file, and load the DLL from that file.

Obviously, there are major security issues with doing that. In addition, where would the file be cached?

So, it's possible, but requires definition. So, let's defer it to 3.1.

I understand that in the meantime you are happy with such cases ending in a type incompatibility error.

Or we could give an explicit error message about it.
