The reason I'm asking about backgrounds feats is because of the optional rule that has been introduced recently (from example from GoG):
If the DM decides to allow the giant foundling and the rune carver backgrounds, all characters in the campaign gain access to a bonus feat. If you select one of those backgrounds, you gain the bonus feat specified in that background. If the background you choose doesn't provide a feat, you gain a bonus feat of your choice from the following list:
- Skilled
- Tough
