I argue that things that could be parameters to .transform don't
belong into the codec registry in the first place.

No need for writing directly against the codec registry.
Using some other specialized interface: yes, Yes, YES!

Depends on what I do: when I invoke gzip from the command line,
I pass -9 all the time, as a habit.
Or did you mean "in Python"? It's a long time that I needed to
use the gzip module at all; and the last few times, I suppose
it was always through the tarfile module.
I use gzip so rarely that I find it wasteful that it gets its
own shortcut. If I had a (half-serious) wish for a string
method shortcut, it would be
"GET / HTTP/1.0\r\n\r\n".sendto("foo.bar.com", 80)
Perhaps I should write a codec for that:
"GET / HTTP/1.0\r\n\r\n".encode("http:foo.bar.com")
which sends the request and returns the response :-)

You mean, without looking into the HTML documentation? Sure enough.
"import uu" I remember, then I do help(uu), scroll to the end.
If you can't remember that the module's name is uu, then you probably
can't remember the codec, either:
py> "foo".encode("uuencode")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
LookupError: unknown encoding: uuencode
