Running
emacs -Q --daemon -l test.el
where the content of test.el is
(scroll-bar-mode -1)
(setq default-frame-alist '((cursor-color . "#007fff")))
fails to disable `scroll-bar-mode'. When opening an Emacs client, I
have to toggle `scroll-bar-mode' two times to disable it. The first
time it is "enabled" again (no visible change) and the second time it's
disabled. The problem disappears if I remove the second line.
I'm using Emacs 29 built from master earlier today.

`scroll-bar-mode' disables itself by altering default-frame-alist, so I
think what you're seeing is predictable?

I see, I didn't know. Can I disable `scroll-bar-mode' via
`default-frame-alist' directly?
The problem arose since `set-cursor-color' doesn't work when starting
Emacs as a server so I changed `default-frame-alist' but that enabled
`scroll-bar-mode' ...
Feel free to close this as it's not a bug, then.

Yes, for new frames, you can just set:
(setq default-frame-alist '((vertical-scroll-bars)))

Perhaps this quirk should be documented in the scroll-bar-mode doc
string, though?

Yes, +1. Users shouldn't need to look in the code to
find out that "`scroll-bar-mode' disables itself by
altering default-frame-alist".

I've now done so in Emacs 29 in both the scroll-bar-mode and
default-frame-alist doc strings. (The latter already hinted at there
being problems with setting it directly, but I've made it more
explicit.)
