Currently, if I inspect the code of a revision and also want to make a comment about it, I will need to submit the page two times.
I think if the user post a comment and has marked one of the sign-offs this data should also be submited (saving one page load).
Version: unspecified
Severity: normal
Part of it is because the pager sucks, and it was a PITA with the nested forms and other wierdness
I did try and fix this before

I actually originally wanted all the CR forms to commit changes immediately via AJAX but never got round to doing the ajax submissions or updates. ;)
For now, I agree it's probably best to make sure those subforms are integrated into the whole form which operates on a 'change a bunch of stuff and commit when done' model.
