You should have a neutral where one is needed. Switch legs don't need one, nor do many multiphase circuits.

Codewriters are now requiring people to install additional conductors 'just in case' which, while good practice shouldn't be law.

It absolutely should be law.

It's not the 1980's anymore, and there's no reason to be designing or building houses without the necessary electrical system to utilize modern consumer technology.

There's nothing additional to install, you just can't cut corners with cheaper 2-wire cables anymore.

...whether you want 'smart' switches or not.

I'm reminded of when I built my house and installed old fashioned shower and sink valves in my bathrooms. The inspector initially refused to sign off because I didn't have modern fixtures.

No, this isn't something that needs to be mandated.

If you're "installing" individual conductors you have much bigger problems
