The point is that Wayland architecture is designed to discourage such API, secure or not (I'll also have to check, but AFAIK Wayland went with even less security support in protocol than X11[1] - not XFree/XOrg - so retrofitting is even harder). Same with accessibility et al.

Honestly, Wayland by design feels like MVP that forgot that outside certain limited systems they are missing a lot of "filler" APIs, and somehow assumed it would magically happen by itself. Unfortunately there's no DCOM on Linux in practice, and D-Bus is much more annoying to program against, so the expected "do it in D-Bus" never materialized (and was supposed to cover even things like copy-paste in the original discussions).

[1] X11 servers from vendors other than XFree/XOrg had things like advanced access controls over what applications could do, some integrated with OS-wide Mandatory Access Controls. There's also the forgotten (by most) part of the protocol for secure entry that one is supposed to use when accepting passwords and the like.

FWIW I think the goal has been to put security in some other layer that's more appropriate. You can add those type of APIs to Wayland but you'd have to also implement a security mechanism, which is non-trivial. D-Bus can be the most secure option for some things but not here, there might have been a plan to put the clipboard in D-Bus but I believe that got scrapped because it was found to be less secure; Wayland implementations are supposed to validate access to the clipboard based on the most recent input event, to prevent background applications from snooping on the clipboard.

Personally for me I do find D-Bus to be easier to program than Wayland though, the libraries for it are a lot more mature. You might want to try something like pydbus or systemd's sd_bus, or the Rust library zbus. Those are some of the better implementations I've seen.

X11's security mechanisms were never really complete, I don't know of any distribution that actually uses those Mandatory Access Control schemes. Distributions that focus around X security (e.g. Qubes) all seem to use X sandboxing now which should work better than MAC-based security but is quite complicated to set up and still not practical for most other distributions to use. I remember seeing some MAC-based proposals for Wayland but they never caught on because the focus there has also moved to sandboxing.

AFAIK there is no special part of the protocol for this and this was never really a good solution. It's just done using an ordinary keyboard grab, which are mostly considered an insecure API that does nothing in practice because all the other X security schemes will try to disable or restrict grabs for security reasons.

Ah yes, security through magic fairy. To their credit, at least they went with "you can't break security through nonexistant feature", except a lot of those features tend to be critical for open desktop.

D-Bus is still way more problematic to work with than DCOM. Even on the operation model (something that generic libraries will always have hard time papering over).

As for the X11 extensions - no Linux distro (at least on open market). Because XFree86/X.Org != X11. In fact, XFree86 was essentially lowest common denominator, using with little change a design that wasn't specially good back in 1992. Even if glamor helped some of it, it was more a bandaid than rearchitecting the server (which could have been done without changing protocol).
