Interesting.

1. The sequence is generated in a separate transaction before being used.
(state/sequence.go)  So I don't think your concern about obtaining and
using in one transaction will be an issue.
2. We have not had much discussion around strict ordering of actions being
run in the order they were queued.  My impression is that two different
users interacting with the system at the same time is a bit of an edge case.
