The relevant increase in security took place in 1997. Prior to that
point, every thing I know suggests that the security requirements were
ambiguous, at best. All that happened is that flight recorders that
could not have been approved under 1997 specifications have been
downgraded to the next lower level. Perhaps they should have been
downgraded in 1997, perhaps the specifications shouldn't have been
changed in 1997. I don't know, because I wasn't involved.

If you think the 1997 security requirements were too strict, I think the
onus is on you to propose and justify a set of requirements that you
would consider to be more appropriate.
