You can disable this warning. Run the following command in Terminal:
defaults write com.apple.finder FXEnableExtensionChangeWarning -bool false
Then relaunch the Finder, either by Option-clicking on the Finder's icon in the Dock and choosing Relaunch Finder, or by running this in Terminal:
killall Finder
(I found this when browsing through the long list of defaults commands that we recently published as a hint. But when googling it, I noticed that OSXDaily had recently published. So a shout out to them.)
