It still works actually, it just prints a warning stating that it’s
deprecated. (I’m used to ‘-d’ as well but I’m confident my muscle
memory will get used to ‘-D’. :-))

It’s unlikely because if you do “guix gc -d /gnu/store/…”, it still
behaves like before.
Does it address your concern?

It’s still safe, I do the same as you! The intent is just to provide a
simple way to “remove old stuff” (currently you have to know that you
have at least two profiles, and then run ‘guix package -p … -d’, which
isn’t very convenient when all you want is to free some space.)
Thanks for your feedback!
