Most permissive licenses are very close to CC0 but with a few key differences that are honestly not a bad idea. Like for example having to retain the original copyright notice is alright because it at least gives credit to the original author.
I do use permissive licenses sometimes, but only on small trivial projects that anyone could put together in a single evening, like my "gotobed" program.
But on any project that has a significant size and requires multiple months of work to achieve, like my "Libre-PL2" program for example, I will obviously the GPLv3-or-later to ensure users will always have freedom when they use it.
