@mgorny use REUSE.software and SPDX headers and everything becomes larger than the GPL notice.
Though, I went the other direction over time and I'm more likely to use MIT/0BSD than GPL simply because nothing I write make a difference to be copyleft-licensed, but it can make a difference to be permissive-licensed.
@flameeyes @mgorny And when it makes a difference ... you might regret it.
