Leland, I appreciate you desire to serve your customer best. I, also, do many things that are not required by code ...
OR, at least, not according to some, who use 'code' as a design guide. That might mean a few more receptacles and switches ... but I try to make the place livable, and not something to sneak past the planning department.
Still, there's a world of difference, in my mind, between what's 'legal' and what's 'right.' I've seen plans where the phone / data were left off - and have always raised the issue.
I make the distinction ... and I cannot, in my greatest stretch of the imagination, include a phone jack as essential to the minimum needed for safety ... which is what Article 90 tells us is the purpose of the NEC.
Let's not confuse what's 'better' or 'nicer' with the bare minimum. That's where the code panel and I disagree.
