TLDR: Do you know of any uses for MassMessage, where it delivers identical
content to the same page multiple times? E.g. content *similar to* a
user-warning template, where everything might be the same except the
timestamp.
I ask because we're trying to determine whether there would be any problems
with a proposed solution (using "De-duplication") for the rare bug where
MassMessage can post the same message to the same page multiple times due
to JobQueue issues (see tech details in phab:T232379#5480718
<https://phabricator.wikimedia.org/T232379#5480718>).
I.e. It would make it impossible to send *exactly the same message* to
the *same
page* regardless of timing.
Would that cause a problem on any wiki that you know of?
We think not, but want to be more certain. Thanks.
