Yea!

The Wikisources individually deal with poor OCR scans, and have multiple cases of the same typo through a set of scans; that often replicate through series of works. So having the ability for a wiki to set things that will fill things like

"wliere" for "where", "tvvo" for "two", "coUect" for "collect", "prcsently" for "presently", and "written bv the" for "written by the", and "they aiso" for "they also"

(borrowed from @BD2412)

having them as individually grabable sets, and potentially reusable would be brilliant.

At the Wikisources, we could utilise an AWB subpage based on the Index: namespace of a work
eg. for the work at https://en.wikisource.org/wiki/Index:Federal_Reporter,_1st_Series,_Volume_1.djvu
the gen fix page could be at https://en.wikisource.org/wiki/Index:Federal_Reporter,_1st_Series,_Volume_1.djvu/AWB

The other opportunity that I see is some sort of Special: page, and have proposed something like that to @Pathoschild for his development of [[m:TemplateScript]].

I see that these maintenance type functions by bots or semi-automated could look to discuss an agreed and similar approach to the next development schema, be it a new/dedicated namespace or special pages, or something that the greater minds can envisage.
