Debian's which hunt

Debian's which hunt

I had not heard of command -v before I wanted to see what it was like on Fedora/CentOS. On my older CentOS box I got:

$ command -v which
which
$ which which
which ()
{ 
    ( alias;
    eval ${which_declare} ) | /usr/bin/which --tty-only --read-alias --read-functions --show-tilde --show-dot "$@"
}

on a newer Fedora box, I got

$ command -v which
alias which='(alias; declare -f) | /usr/bin/which --tty-only --read-alias --read-functions --show-tilde --show-dot'
which which
alias which='(alias; declare -f) | /usr/bin/which --tty-only --read-alias --read-functions --show-tilde --show-dot'
	/usr/bin/which

Both are based off of https://savannah.gnu.org/projects/which/ 2.21 so I wonder how much it will break Fedora to change also.
