Is this a regression?

No

Description

When using CurrencyPipe I expect it to default the currency to the locale supplied by LOCALE_ID, not to USD.

https://angular.io/api/common/CurrencyPipe#description
From the docs:
"Deprecation notice:
The default currency code is currently always USD but this is deprecated from v9.
In v11 the default currency code will be taken from the current locale identified by the LOCALE_ID token."

From this description I would expect from v11 onwards, that USD would not be the default currency, but the wording is confusing so I'm not sure if this is intended behavior or a bug. If this is the intended behavior, maybe we could make the docs a little bit clearer.
