In reply to @python36_08342 "Hi everyone! I’ve been": I think I've written my
thoughts on this elsewhere but to my knowledge there is no current official
process for this with respect to nim-lang/packages.
I for one would be upset if I select a package written by one author (implying I
trust their code and security practices) and receive something written by
someone else.

Answers:
1. I think allowing users to "take" an existing package name without the consent
of the original maintainer is needless and a security risk. Submitting a package
with a new or slightly altered name is fine though to me (license allowing)
(please don't use a nim- prefix they are all nim libraries lol).
2. Not currently, I've argued that it should only be acceptable with the consent
of the original maintainer.
3. Make a new package and announce it on the forum. If someone needs an
up-to-date i18n library they can update their own deps to point to the updated
package.
