For those types of systems - lack of a true audit log is probably a bigger barrier. The biggest "missing feature" are
goingto depend on your problem space.

Whether this is acceptable depends on your system. Yes they can be recreated with a number of caveats
-performance for many systems will be poor until some (or all) indexes are back. If you have SLA's based around
performanceyou can extend your outage until the indexes get rebuilt.
-Indexes are used to enforce primary keys. Are you comfortable running temporarily without your primary keys?
-Some replication engines rely on primary keys or unique indexes. Losing these could break replication for you.
I think if you could control this on a per-index basis though it could be a win.
