Why should I not use VSAN 1?

[atthomasnjm]

Looking for reasons on why VSAN 1 should not be used, besides it is best practice.  I have seen environments using VSAN 1 on both fabrics, and could not come up with any good reasons.

VSAN 1, also known as the default VSAN, is typically used for communication, management, or testing purposes. We recommend that you do not use VSAN 1 as your production environment VSAN. There are several features that, when configured, disrupt traffic on VSAN 1. If you use VSAN 1 as your production environment VSAN, you risk disrupting traffic when these features are configured.

Thanks for the info Vu Phan, my other question then is what features disrupt traffic in VSAN 1.  Cisco docs do not seem to spell them out.
