Keyboard cues are disabled by default on newer versions of Windows. Some win32 common controls, e.g., button doesn't draw a focus rect when SystemParametersInfoW(SPI_GETKEYBOARDCUES) reports FALSE.
Drawing a focus rect when the button is really small creates an effect that makes the button look corrupted. On Windows, the focus rect is not drawn when keyboard cues are disabled, which is the default.
Other controls also have this behavior, so they're included as well. There are some exceptions, for example, SysMonthCal32 always draws a focus rect, even when keyboard cues are disabled.

It's more complicated than that. There are dedicated messages WM_QUERYUISTATE/WM_UPDATEUISTATE/WM_CHANGEUISTATE. So this state is dynamic, but probably changes only one way. On modern Windows you don't get focus rectangles by default on buttons, but you can get them by pressing "Alt", that's how it worked from when this UI change was introduced. It applies both for focus rectangles and keyboard accelerators.
What I imagine we need is to send WM_CHANGEUISTATE to a top level window, let default procedure propagate it using WM_UPDATEUISTATE, and then react accordingly in controls.
Button v6 (or maybe all controls in v6 variants) works differently - newly created button does not have a focus rectangle, until you press Alt. User32 button "inherits" this state probably, and creating new button shows focus rectangle right away.

Same for this one. Afaict focus rectangle is always visible.

I am aware of WM_UPDATEUISTATE, but I didn't know that pressing Alt could turn on the focus rectangles dynamically. And I thought since we don't support WM_QUERYUISTATE/WM_UPDATEUISTATE/WM_CHANGEUISTATE in Wine at the moment, we could just use the sysparam state.
On Windows 10 22H2, you call SystemParametersInfoW(SPI_SETKEYBOARDCUES, 0, 1, 0) to turn on keyboard cues. And then comctl32 v6 buttons will have a focus rectangle by default, without pressing Alt. This seems to contradict what you said about comctl32 v6 button not showing a focus rectangle until Alt is pressed.
Even with Alt being able to turn on focus rectangles dynamically, I am not sure it's worth it to add support for WM_QUERYUISTATE/WM_UPDATEUISTATE/WM_CHANGEUISTATE and Alt handling in DefWindowProc(). The focus state can be manifested by the theme part state now. So having a focus rectangle is actually redundant.
Anyway, what I am trying to say is that I would like to delay implementing WM_QUERYUISTATE/WM_UPDATEUISTATE/WM_CHANGEUISTATE and Alt handling until a real-world application needs it.

I haven't tried with SPI_SETKEYBOARDCUES, I was talking about defaults.
Disabling cues unconditionally or by this parameter that users don't interact with, is wrong. This will make it impossible for people to use keyboard navigation in dialogs for example.
Not implementing this with correct messages will also potentially create inconsistent behavior between any custom controls, and system provided controls.

I used Windows 11 21H2. Right from the start it won't show a focus rectangle, but moving to another item with keyboard shows it.

Okay. I will see if the customer is willing to cover the cost.
