With recent news renewing broad interest in self/peer examining
the security of the entire spectrum of products... has the FreeBSD
implementation of GELI/crypto/random published design papers,
presentations and reviews? Are these collected centrally for easy
reference by the community?

Quick ref:

Further, and more generally on the higher level meta topics we've seen...
How is FreeBSD working with the community regarding possible
updates to cipher suites, embedded crypto libraries, and the like?
Similarly, how is it approaching the movement towards end-to-end
toolchain integrity... from the repository, through deterministic builds,
and on out to secure distribution and updates?

This should be viewed not as a pointer but 'While we're on the topic,
hey, how are the FreeBSD folks doing' :) Presumably this subthread
could migrate to freebsd lists for those interested in following the
details more closely.
