That’s easier said than done. First of all, changing the standard is non-trivial in general but here we have another complication of multiple different and incompatible implementations of ‘which’.

Debian's which hunt

Eh... you could take the echo(1) approach and basically say "If it's on your PATH and not an alias, shell function, etc., and you don't pass any flags, then output looks like it did in csh, otherwise the behavior is undefined."

(Yes, there are implementations which will print something funny if it's an alias, shell function, etc. See for example the builtin which in zsh.)
