SAL pages like https://wikitech.wikimedia.org/wiki/Nova_Resource:Tools.wikibugs/SAL (and certainly https://wikitech.wikimedia.org/wiki/Server_Admin_Log) often grow to a point where it is both difficult for MediaWiki to render the page and for users to find useful information.
I tried to apply archivebot.py to keeping SAL pages readable via archiving, but as @MarcoAurelio kindly pointed out that script does not understand how to deal with SAL which is not structured like a Talk page full of signed messages.
Stashbot uses a consistent method for adding content to SAL pages. This algorithm should be documented clearly somewhere that does not require source code analysis. That could then be used to generate requirements for an archiving script to be added to Stashbot itself or as a pywikibot script.
