Release notes say that

> This is the first release of the V9 architecture, including the following optional features:

> TRBE (Transaction Record Buffer Extension)
> ETE (Embedded Trace Extension)
> SVE2 (Scalable Vector Extension 2)
> TME (Transaction Memory Extension)
> BRBE (Brach Record Buffer Extension)
> RME (Realm Management Extension)

So if one makes a v9 cpu without any of those features, in what way does it differ from a v8 cpu?
