Which is something THEY want to avoid.
Setting purity tests, opens up economic popularity contests I think they would like to avoid.
Genres tend to rise & fall, the HoF is looking to maintain importance no matter what's in vogue.
I think it started as the Rock & Roll HoF for the name recognition, but they want importance of being musically relevant across a few genres.
Are we sure about this... At times and given who they are putting in, it would appear to be all about the popular vote! I can see it both ways when it comes to changing the name... or not changing the name.
