Well, as far as I can tell, the so-called "Job Ticket API" is a replacement that does generally provide the required functionality. The problem is that many printers (even relatively new models) e.g. use PPD files with vendor-specific keywords for some funcationality and don't support the same functionality using IPP (Internet Printing Protocol) even though equivalents would exist, meaning the functionality is not available via the "new API". Some more information also in CUPS issue [1]. I'll also post a link to this discussion and QTBUG-56545 there, in case anybody from the CUPS community wants to join... As far as I know, the plan is to develop/use so-called "Printer Applications" to allow using such functionality to work with new new API without having to be done in CUPS itself, but that needs more work elsewhere and does not "just work out of the box", so it would IMHO still be a bit over-hasty to drop the use of the PPD API functions right now, breaking existing printing use cases in practice.

This is https://bugreports.qt.io/browse/QTBUG-56545 As mentioned there a few years ago I don't think there is a CUPS way to do stuff like "printer supports stapling" using non deprecated functions.

[Development] Volunteer wanted: update use of CUPS API
We have plenty of warnings when building the CUPS plugin to QtPrintSupport
about deprecated methods. See attached.
Any volunteers to go fix this?
