Trying to figure out the best solution for maintaining a monorepo (MR) of packages.

I see that many blog posts recommend using MR tools such as Lerna/Nx together with Yarn workspaces, as Lerna is used as a "high level wrapper" to "lower level" yarn.

So I've been asking Google this question for few days now, still not sure that I understand, trying my luck here:

"What can be done with Lerna (or nx/turbo/other MR tool), that can not be done using yarn workspaces?" Thanks in advance!
