Just to be 100% clear, existing Org menus will not disappear any time
soon. Even if we change menus to transient, I will make sure to leave a
customization to switch back.

New menus will probably use transient/other external menu UI though.

As for your response, I will provide some comments, but I also suggest
you to send a bug report to Emacs, so that Jonas has a chance to pay
close attention.

In other words, you need visual-line-mode inside transient buffers. Do I
understand correctly?

I think you can bind SPC and DEL in `transient-base-map' to make things
easier for you. I agree that SPC/DEL doing scrolling are expected from a
menu.

How do you usually know it?

On my side, there is an indication after I customized
(setq-default indicate-buffer-boundaries 'left)

This sounds like an omission. Again, you can use `transient-base-map' to
work around, but it is better to be discussed as a dedicated bug report.

AFAIU, org-fast-todo-selection interface was never scrollable. At least,
it looks like it was the case 17 years ago. May I know more details
about which exact menu you are talking about and when did scroll stopped
working? I may be missing something.
