It's not any less code, but gives us much better control over how they're called, eliminating the need for global temporary macros for passing what really are command arguments.
No functional change, but paves way for future programmatic switches such as perhaps binary/ascii signatures.
This is of course incompatible with folks who have their own custom %__gpg_sign_cmd from the past, recipes for these have unfortunately commonly floated around the internet as "necessary" for signing. These are double-underscore macros, people messing with those had better know what they're doing.
