The later isn’t going to scale well: the client will take longer and longer over time as more and more packages get registered to a source. Also takes longer as a function of total number of release versions a package has because we are collecting metadata for each version. Rather not ask users to just get used to developing more patience over time.
I am not sure how strong the effect might be but this is definitely a

What about the "info" command? If a package is not installed it would be
nice if the command would obtain the latest meta data from the package's
repository as well.

That sounds great to me! This would be exactly the behavior I would
expect based on other package managers I have used so far.

Thanks for the clarification. Automatic removal might be a bit
aggressive but a warning would be very helpful I guess.
