Default verbosity on v20.0.0b1/Win10 gives no output; '-v' gives too much to serve as a concise summary of the actions taken

[bskinn]

A bit more output in the default verbosity would be nice; perhaps not identical to the prior incarnation, but on that level of detail.

Thank you for all the work on this!!

I actually like the new "quiet" default.

[bskinn]

I'm sure I'll get used to it if that's where it stays, but I'd prefer at least a short happy-path Environment created or Environment created in {PATH} message.

CLIs that don't say anything about what they've done make me a bit antsy.

[gaborbernat]

@rbtcollins dunno; not having output if there's no warn/error seems to be sensible. Neither mkdir, touch, rm commands print stuff 🤔 It's more in Linux Mantra.

[gaborbernat]

The single -v prints one line per phase (5 overall), so I think it's sane IMHO. 🤔

[bskinn]

Yeah, but creating a virtualenv is a more complex operation than those POSIX commands are.

No, sorry, I wrote poorly -- I think the output that -v produces is great for a -v invocation. It's just that there's no middle ground between no output by default, and the -v output with -v.

[bskinn]

More broadly, apologies for diving right into a bikeshedding discussion -- it's working so well so far that this level of nitpick is the only issue I've had!

[gaborbernat]

There were a few duplicate information on the single verbosity, addressed part of #1511

[gaborbernat]

I'll close this now as I tend to agree with @pfmoore that the quiet mode by default is fine. It also mirrors how venv operates. If more people will comment on this issue we might add some type of report generation in some shape or form. Thanks for starting a discussion about it.
