We have certain scripts that mass categorise, mass delete, mass edit, mass protect, and mass rename. However there doesn't appear to be any scripts that can mass replace text on all specified pages. Mass categorise and Mass protect have features like that, except they don't mass replace words across a specified list. They mass categorise and mass protect across a specified list respectively.
FindAndReplace is very handy when finding and replacing text on single pages, but if someone wants to be able to replace text on hundreds of pages, that would be very time consuming, to use FindAndReplace for the job. Currently I'm cleaning up tons of red links on pages, but it's very tedious to have to do manually. AWB may do the job, but it only works in certain namespaces, such as the article namespace, and my PC is outdated and no longer supports AWB, so I wouldn't be able to use it for that sort of thing anyway.
The user talk namespace for one. It would be handy to get replace a red link across tons of user talk pages belonging to anonymous users, to lessen the number of wanted pages. And the MediaWiki namespace isn't compatible with AWB either. AWB automatically skips a page when I try to do automated edits to it, if it belongs to a certain namespace, even as an admin.
I wonder how easy it would be to make this kind of script. I know I certainly don't have the experience to make one, but I wondered how easy it would be for someone with the experience to be able to make one.
