I'm not sure I agree, to me the difference between JRPG and RPG is like the difference between anime and animation. In a western audience, the label has been coopted by games closer to home with tropes we're more familiar with. That doesn't make the labeling of Japanese media othering in that sense, so much as it allows us to understand what contexts it is both from and for.
I can see how, to some people, it might be a turn-off (just see all the people that turn their nose up at anime conceptually even if they'd like it) -- see the people that may have seen edge of tomorrow in theaters and enjoyed it, but would likely sneer at being told to read all you need is kill, differences in media notwithstanding. But as the media landscape changes and grows it's useful to have different ways to sort of illustrate the differences in audience as well as the differences in creative context.
