That's basically what I do.

They don't run just because they are there. Well, I could add the
symlinks in /etc/runlevels/default which is what rc-update does, but
that's no fun.

We enjoy the flexibility of the scripts because they provide a
convenient way to glue the system together. For example, several
packages contribute kernel modules, and it's a hook script where we
call 'depmod -a' to create a consistent view of the entire
system. Much like env-update is called from a hook to gather
environment settings from different packages.

We sign ISO files, this involves ECDSA and smartcards. I cannot tell
you more, or I'll have to kill you. (Honestly, I don't quite
understand what's going on exactly.)
