IPMC/Shepherd notes:
Dave Fisher: This podling thinks they are near graduation, but has never
added any new committers/PPMC members. Not so sure. I sent a message to the
podling about this.
Alan Gates: This is my fault. See email thread
https://lists.apache.org/thread.html413e06bde2263f2f56797e871b256ec1584f8c5
41fdc5e96857b13f5@%3Cdev.tephra.apache.org%3E where I started pushing them
towards determining their future direction. I assumed they had added
additional PPMC members without checking. I can take this feedback back to
them and help them work through this.
James Taylor: I've updated the community assessment to "Community building"
based on the above feedback.

Comments: Sent following email to dev list after reading this report:
It seems development on Tephra has slowed quite a bit lately, with only 7
JIRAs filed during the last 3 months. I know Tephra is used in other
projects, like Apache Phoenix. Is this slowdown temporary? Is development
slowing because Tephra is mature and only maintenance is now required? Is
it continuing to be picked up by new projects or only used in 1 or 2
places? I ask because it feels like it is near time for Tephra to graduate
(it's been incubating for over 2 years now) and what needs to be done to
graduate is somewhat determined by the answers to these questions.
