you're VERY right. in a nutshell, the things you're describing are
regrettable cruft I didn't have time to roll patches for in version 5.
In drupal 6, what I'd REALLY like to see is the elimination of nodeapi's
'view' and 'alter' hooks entirely, mapping them to a separate
hook_node_alter(). Why? Nodeapi is horribly overloaded (horribly!). When
we have params like $a3, $a4, and $a5, and they mean different things
for each op, it's a sign. ;)
As everything moves into #keyed arrays (forms, node bodies, profiles?
mail? etc), using standard methods of altering, then rendering, the same
structures in different contexts will bring us huge benefits.
RSS feeds, print-friendly output, and standard node output need to share
the same rendering path. That's another one of my 6.0 to-dos. So. If
you're interested... let's talk. Let's patch ;)
