No. The grammar of BASH includes history expansion in double-quoted 
strings. Only single-quoted strings protect against history expansion.

If by "should" you mean to express a disagreement with the authors of 
BASH on when history expansion should be active, well, that's your 
prerogative, but it's not how things are.

We're talking about computers here. If we don't speak their language, 
desired results cannot be exected. If there's a command interpreter 
you'd like to work with and it doesn't exist, you'll have to create it 
or commission its creation yourself.
