I'm pretty sure I've pushed back on this before, but my views have evolved after searching the forum for related topics.

I searched for mv content/index.md content/_index.md and found 12 topics where I had typed that command.

There are tens of other topics where the user created contentDir/index.ext instead of contentDir/_index.ext, and I or others provided the correction using something other than the command string above.

If we can do this, it would help to eliminate a dead-end for new users.
