Agreed, not to worry. I've played a few '53 Les Pauls, which are set necks & a bit more that 15 years old, & they were rock solid. I also once got to play a New York Martin (1833-38) & it was also fine - but the owner was a top-notch luthier, so I couldn't swear that wasn't due to a reset. I've also recorded a guy who plays an 18th (or maybe it's 17th) century violin, & while he did have technical problems, it wasn't due to a loose neck (Man, quoth he, you spend a million bucks on a fiddle and a two-dollar rosin bag doesn't work!)
