Again
The assumption cited by Wolfheart that the PC/Origin/Companion will all have the same freedom to respecc to level 0 is.....an assumption.

The storylines/narratives of the companions are tied to their race/class. Level 1 dip is mandetory. Certainly a 1/11 multiclass is viable.

Honesty Halsin not a druid? Wyll not a warlock or Shadowheart not a Shar cleric? At least one level?

Nah. Larian isn't going to waste all that effort
