Well as with any addon, unless the other person has it installed - they won't hear/see what you are doing with the addon.
On the related note:
While I see the logic of evasion/dex being slightly higher for hatchlings due to their smaller size, I do NOT see the devs implementing anything that makes staying and playing as a hatchling any "eaasier" because its not meant to be played that way.
One could turn around and argue that baby animals are not necessarily more evasive or more dexterous than their adult counterparts because they don't have the fine motor skills annd muscle control that an adult has. A baby elephant isn't more graceful or more agile than its adult counterparts simply because it doesn't control itself as completely. Anymore than a kitten; which any cat owner knows, is not at all more agile or more capable of dodging things than a full grown cat.
"But the hatchling gets older and learns!" Yes, but its not intended gameplay for you to be level 100 and have benefits over an adult who is level 100.
Hatchlings, since day one, were meant to be WEAKER than equal level bipeds, harder to play, and slower for that fact - to adjust for the fact that the idea is you are a BABY creature. To motivate players to want to be adults and equal to bipeds(whistles)
, or ancients and stronger than adults.
I see one side of this "making sense", but from the other side the logic doesn't hold true. And at the end of the day, you aren't intended to be better at anything than an adult. Because you are not intended to stay a hatchling for your game play career (same as you there are things you have to be ancient to receive, you are not intended to stay as an adult).
Just because players can choose to do so, doesn't mean the devs will reward those choices.
(Now I fully understand that even with a bonus to evasion/dex that reduces when you level and the perks overtake such an early bonus means the hatchling still will not be eqaul to an adult. And as such, such a bonus doesnt bother me. Just wanted to remind those who perhaps never knew, that hatchlings were meant to be more difficult to play than a biped due to being a baby creature. And also to address the idea of making a hatchling a more viable leveling character past its intended levels).
