Re: [Extra] SNIPPET (now PREVIEW) draft update

The arguments for octets are storage space and network traffic, which is octets, but I do see your point. Should we say 255 characters maximum then - obviously servers can still do less, and clients can choose to truncate. 

Either way, we'll make sure JMAP aligns.

Unless you have a strong reason to lock it down to 200, would you consider changing it to "no more than 255 octets" with an understanding that there's no requirement that servers have to store that much, just that clients must be willing to accept that much. That will keep everything consistent.
