you think they are so important, but actually i don't think any of them is used a lot...
as for "having" to fix it, no one here has to fix anything. Those modules are 3rd party, and therefor not supported nor maintained by the anope devs. Like chaz said, those modules, and even anope itself, is written by volunteers. It s not like you are paying for the stuff, in which case you would deserve support, but anope s free, as are most modules. And when a module author stops maintaining his/her modules, they will become dated eventually.
Though still available a lot of the modules are no longer maintained, and those that still work should ideally be rewritten to use the 1.7 module style
anyways, i did modify os_antiflood a while ago to work with svn, so i guess it should work on .16 as well...
