Yeah that doesn't work with things as hugely hyped as the cloud, agile, etc. Obviously it's a cult and it doesn't solve anything in and of itself, but you're not allowed to say that.

Rather, I'd go for:

"Let's solve this problem we've been having with Azure Cloud Functions!"

"Of the top five things that we are trying to build, let's build them with Agile!"

Otherwise, you are not a team player, part of the problem not the solution, etc. It sucks, but that's politics.
