Add variants

[ionas]

• GPL2 -> You may also consider EUPL
• MIT -> You may also consider BSD

etc... people would have to dig for more details themselves.

Not seeing lots of similar choices is a feature, not a bug -- #320 (comment) "The more choices we present, the more cognitive overhead we require"

I'll leave this open though and consider listing licenses with the same features someplace innocuous, perhaps on individual license pages.

Thats good too!

I think it is a bug since BSD is probably pretty common.

Showing it as a variant is a feature, though.

Good

Opened #1364 — optional related: metadata, sidebar partial, MIT/GPL/LGPL links.
