I hereby propose to create a common way for bot classes to 'pipe' the changed text to other classes without saving it directly to the wiki. So, botops could do something like: python pwb.py pipe [generator] scripts/harvest_template [options] + scripts/weblinkchecker [options] + scripts/replace [options] to make custom replacements, check external links and enrich Wikidata with a single edit (except for the Wikidata import process).
