@Hamilton_Abreu, thanks a lot for finding and reporting all these details. I find this really helpful, and I will always happily review and merge patches that fix such details. But: Please do not open individual Phabricator tickets for each individual mistake in a message. This creates a huge amount of overhead for the people working on this. Instead please create one ticket for one extension, and list all mistakes you find in the tickets description.
In case you don't know which message belongs to which extension, you should still list all mistakes you find in a single ticket. Others will find out and split the ticket for you. This is still easier for everybody.
This would be really, really helpful. Thank you.
