Hi,

I agree...

...but I am not convinced. :-)  For instance, about discoverability,
assuming "guix install / remove" would not be an alias of "guix
package", then I would go va "guix help" then "guix install --help"
then probably via "guix help" again, then "guix remove --help" etc.
An extreme counter-example to your "clearer" point about subcommands
is Git: I do not consider such many subcommands more discoverable
because it gives the impression of a scattered mess.  Subcommands
provide a thematic hierarchy.  For sure, it is a balance. :-)  Because
Guix is doing many many things, it is hard for people to understand,
IMHO, therefore a sub-command hierarchy helps for catching the Guix
features... I digress. :-)

Well, my point is, for example, the logic of "guix system" then "guix
system <action> <--options>" appears to me easier to grasp and
discover.  Idem with "guix import".  I think "guix vm" or "guix image"
would not ease the discoverability.  What is unfortunate with "guix
package" is that <action> and <--option> are both using dash-dash.
Another story. :-)

I am not convinced that promoting a niche use-case would be a good
idea.  For what my opinion is worth.  Well, I trust your experience if
you think it is better.

Thinking about it, it would be the most coherent from my point of
view.  And idem for --export-channels, no?
