Indeed, these can eventually be removed; naturally, a bigger portion
of these changes go into the conversion functions into the new layout.
The interpreter part itself is conceptually the same, seccomp as you
might have noticed actually got a lot easier thanks to the BPF
changes, and the new instruction layout is much easier to handle for
JITs (i.e. the BPF extensions), which is ongoing work. Clearly, there
are successive integration steps required. As such, also the
documentation will get further improved for all that in the next days.

Thanks,
