Proposal: include translations in installation tar/zip
Overview
The default language of CiviCRM is en_US. Other languages are not included in the standard installation package.
Looking at the countries and languages on stats.civicrm.org, we can see that a big part of the community is using another language than en_US.
It would be more inclusive and respectful to include all languages in the standard installation package.
We should practice what we preach in our code of conduct: "Communities mirror the societies in which they exist and positive action is essential to counteract the many forms of inequality and abuses of power that exist in society."
Current behaviour
If you want to install CiviCRM in another language than en_US, you need to manually download the l10n file, and unpack it in the appropriate folder. This is an extra (technical) step for non en_US speakers.
Proposed behaviour
Include all languages in the standard installation package, or dynamically load the requested language during installation and upgrades.
