The Viashino creature type is being phased out and errata'd to Lizards

Question:

Hi Mark, laughing jasper flint is a lizard rather than a viashino, is viashino being phased out in favor of lizard? If so will older viashino be errata’d to match?

Answer:

The Viashino creature type has been changed to Lizard. The creatures are still Viashino from a flavor standpoint.

This follows their phasing out of Nagas to Snake

What do you think? Good move to simplify things or is removing creature types a step too far?
