Do you mean a ground?

No. Current code as of NEC 2017 requires that all j-boxes with a device have a neutral wire. This includes switches. The neutral wire gets capped off when not used by the switch.

It's to allow for potential future devices like smart switches.

Good Lord what a mess.

Not really. You should have a neutral in your boxes anyway

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
