Actually, I don't think systemd touch the kernel default here.
See consoleblank= parameter
https://www.kernel.org/doc/html/v5.2/admin-guide/kernel-parameters.html
Some years ago it was set to be disabled by default, previously had some
other value.
interesting, I had missed that it had been disabled in

Subject: [PATCH] tty: Disable default console blanking interval
BugLink:
http://bugs.launchpad.net/bugs/869017
Console blanking is not enabling DPMS power saving (thereby negating any
power-saving benefit), and is simply turning the screen content blank. This
means that any crash output is invisible which is unhelpful on a server
(virtual or otherwise).
Furthermore, CRT burn in concerns should no longer govern the default case.
Affected users could always set consoleblank on the kernel command line.

I guess I can take back my previous mail if this works with plymouth
(not sure if it is strictly console ?), thank you for pointing that out.
