This would not be a complicated change as it requires creating a new
version script for those modules.  You can look at commit 20eb273 as
an example, and the work is even simpler now that we just need update
scripts when bumping a module's version (those named foo--1.0--1.1.sql
and not foo--1.1.sql).  Here is the related documentation:
