App Store Optimization: Individual localization for English (U.S.), Australia, Canada and U.K.?

I have an iOS app that is available in all territories and its primary language is set to English (U.S.). I've also created store listings for Australia, Canada and U.K., but I'm using the same localization as for the primary language, since I only have localizations with American spelling.

What happens if I remove the redundant App Store localizations for U.K., Australia and Canada? Would customers from the U.K., Australia and Canada still get the primary language's App Store Information or would it result in a negative impact on App Store Optimization?

After almost a year of observation, it appears that it does not have a negative impact on ASO.

This is because my primary language English (U.S.) is used for Australia, Canada and U.K. as well.

So the other localizations were redundant, given that they were a copy of English (U.S.) anyway.
