I put this into the thread Stefan Kangas links here also, but:

I had trouble finding this button.  Looking a little bit into startup.el
suggests the button to quickly customize inhibiting splash isn't shown,
essentially, unless the slash page is being shown because the user has
explicitly invoked it sometime after startup (I think it's "after a buffer
has been opened", really).

I'm looking using GNU 26.3 on Windows 10 and started digging at
`fancy-startup-screen', called from `display-startup-screen', called from
`command-line-1', called from `command-line'.  I had a very real sense of
'there be dragons' reading startup.el but I'm *fairly* sure that the
conditional logic around whether to display a "concise" version of the
startup page is based on whether there are any buffers opened yet (display
concisely if there are), and that the button mentioned only shows in the
concise view (see line 1771 of the 26.3 release version of startup.el).

I wonder if the logic to display or not display the button is wrong, maybe
unnecessary.

Is it likely people would manually fire up the splash screen to get at this
button?  This looks like it has the same effect as customizing the specific
option and saving the customization which I'm assuming we probably learn
before figuring out how to manually launch the splash page.  I used M-:
(fancy-startup-screen) and (fancy-startup-screen t) after not finding an
interactive wrapper.  The interactive functions in (my version of)
startup.el are `display-about-screen' (not the same info and, obviously, no
buttons for directly changing startup behavior here) and
`exit-splash-screen'.

I'm tempted to submit a patch that simply inverts changes the condition to
~(null concise)~.
*But* should there also be an interactive wrapper to display the startup
screen given it maybe has special-case behaviour just for this that we've
no easy way to get at? (Not on the menu and takes a lambda or user defun to
add currently, I think)

I'm not sure if it's worth repeating my arguments here and splitting

I've responded to both places, I'm afraid.  To your point worse: this is
the better more readable version.
