It's largely down to concerns about action economy and game balance. A druid might befriend an animal (the sidekick rules are good for this), but then they would be treated as a separate party member, rather than part of the druid, for game balance calculations.

NB, Speak with Animals is the spell to use, not Animal Friendship.
