I'm currently not using bgpsec (or rpki for that matter).  BUT, if there
was no path to go back, I would never ever use it.  Destroying my ASN
because I wasn't ready to migrate is a straight-up No Go(tm).

Mistakes will be made.  Rolling back will happen.  Preventing rolling
back will kill the baby and will guarentee this will never be rolled
out.
