There is a huge difference between inanimate objects/classes and babies. Don't personify inanimate objects, they hate that!
On inanimate objects: Aluminium was first ratified by the IUPAC as aluminium⁰, with the agreement of its discoverer Sir Humphrey Davy¹, yet one huge nation calls it something else…
On people: nicknames are a thing, are you saying those are universally wrong? But yes, when a person tells me that they'd prefer their name pronounced a different way, or that they'd prefer a different name entirely, or that they don't like the nickname other use for them, you can bet your arse that I'll make the effort to use their preferred name+pronunciation in future.

First, it's not a baby, that's a ridiculous comparison.
But also, no, not universally even for babies, especially when the name is something ridiculous like X Æ A-Xii where even parents disagree on pronunciation, or when the person himself uses a "non-specced" variant
So why can’t you do that with GIF or PNG? People that create things get to name them.
