I understand that you would like to keep backward-compatibility with
your current tools and ease the switch for your users. But you could
do so by replacing all the shell code in the 'guixr load-profile' by
"guix environment --load-profile". :-)

On one hand, I am not convinced by adding another subcommand as I said
above. :-)
On the other hand, this new subcommand loading a profile could be the
starting point of the "guix develop" subcommand that was mentioned
some time ago.
