I find it inconsistent the way some form ids are named. For example, we have post_node_form for Post content type nodes and comment_node_post_form for its comments. Should've they been named either:

post_node_form
comment_post_node_form

or

node_post_form
comment_node_post_form

Haven't checked how Drupal forms' ids named, but most probably we inherited this mess from Drupal. It's really minor nuance that could be ignored, but then maybe consensus says we should correct it?
