Nowadays RPGs are pretty much always as accessible as the JRPGs of old. Or more accessible, as even random encounters and turn-based combat are increasingly perceived as not streamlined enough.
The question is whether the hand-holding approach makes certain types of games impossible now. For example, if an old RPG derived its appeal from executing successful note-taking, the game can't be made approachable by taking out the note-taking requirement (e.g. with automatic quest logs, quest markers, in-game hints etc) without removing the core of the gameplay.
Though I'm sure there are many other clunky aspects that could be streamlined today without loss.
