Here's the reasoning from the issue tracker:


@frazhome Judging from the number of emails we get about cupsaddsmb
not working or problems with Samba, I don't think that everything is
working as well for people in general.

Since neither CUPS nor macOS comes bundled with Samba, the right place
for this kind of program is in cups-filters (which is used on all Linux
distributions) or in Samba (which covers all Linux/UNIX platforms).

Also, Windows 10 has built-in support for IPP Everywhere printing
now - those clients can print directly and more reliably without Samba.

Looks like we should pick this up and merge
into Samba.
