Regarding communication, just pointing out that the Pywikibot compat deprecation announcement by the Pywikibot team kind of mentioned the API "continue" breakage already by "your bot will most likely break.".

Examples:

• https://de.wikipedia.org/wiki/Wikipedia:Fragen_zur_Wikipedia/Archiv/2015/Woche_23#Pywikibot_compat_will_no_longer_be_supported_-_Please_migrate_to_pywikibot_core

Probably the list of "important" would welcome an update so I've asked for that on wikitech-l and also asked whether *gadget* maintainers have been contacted (as Sitic on de.wp came up with a query for such gadgets).

(as per conversation with @Spage in meeting:) It was mentioned in Tech News w24 and I've added it to get mentioned again in w27.

I think @Elitre is working on the communication of this API break?

This change was announced for months in appropriate venues like mailing lists and Tech News. Despite this, some liaisons decided to spread the word even further on wiki. Wikis which received any kind of notification or are known to be aware of the change are (in some cases, in the wiki's language):
#en.wp
#de.wp
#nl.wp

#it.wp
#es.wp

We don't plan further on-wiki announcements for this change.
