1). opinions on whether you think this change is a good or a bad idea
Not sure. I lean towards bad.
2). if you know of any application using existing <sieveurl-script>
form (with no "owner").
KDE, at least Kontact and kio_sieve.
I have tried to edit my own sieve script using the web browser
Konqueror. It worked, but I don't think more than a few dozen people do
Kontact, on the other hand, might just be deployed and used by a hundred
thousand people. It forms a sieve://... URL when you ask it to frob
your sieve script, passes that URL to the KIO subsystem, which in turn
passes it on to kio_sieve. kio_sieve goes and retrieves the script, or
issues LISTSCRIPTS, or something, and may pass other URLs back.
