And if one were to take on refactoring of OpenACS into NSF, there are other shortcomings that would be strategic to address at the same time.
For instance, adding an 'ad_proc' feature that allows overwriting of release code procs with custom ones of the same name using some kind of standardized glob recognizable file pattern, such as *-custom.tcl in the same package, or maybe in sequential order from any package installed that follows core initialization on startup. This would make it easier to keep custom code separate, while allowing complete intercepts of the standard API.
