----------------------------------------------------------
Stack's questions seem to be at higher level. So allow me to respond to them
first.
bq. Where is WALIdentity in the design doc?
See this thread on the doc:
https://docs.google.com/document/d/1o552MkKq9wF3BXY2nVcsCXBAImUH6r132Cxv9WHL3D8/edit?disco=AAAACOODUIA
bq. Designed or are we trying variations? Or a particular variation?
What is presented in the patch on this JIRA follows what is outlined in the
design doc.
w.r.t. the concrete fields / methods of WALIdentity (and implementing classes),
we're open to discussion and will respect the community's consensus.
