It doesn't have to be written as such in the patch. A send/receive pair
can be bundled together as one object. It would solve a more general
problem of making things more readable in pd which would reach beyond just
[samplerate~] or queries to canvases.
A few convenient shortcuts are sometimes all it takes to make a big
difference in readability. Trying to stick to a minimal set of basic
constructs forces the user to do more work than what would be necessary.

Pd has a cool and very important feature named « abstractions », and using
$0, you can create a unique receiver name without even having to think
about it. No need for dynamic naming.
But if you want dynamic naming, there's [receives] with an s, which allows
a single object to receive from many names at once and distinguish them
while having always 2 outlets. You can use it with 1-element lists if you
want. See this patch (screenshot) :
BTW, [receives] was actually meant to manage large number of GUI objects
matching attributes, method names, and a get-method, without making

You don't give any explanation of why you think it's migraine-inducing. I
don't think that it's obvious why [get( and right-outlet could be more
migraine-inducing than the average pd construct.

I don't remember Czaja's talk in particular, but the idea must have been
in the air back then. Flext 0.4 (nov 2002) introduced Jitter-style
attributes in Pd, and I added my own kind of attributes in GridFlow in
2005 by introducing parsing of the comma in objectboxes so that attributes
setters always counted as ordinary messages.
