To delve into a slight tangent on your final point about the grammatical quirk of writing in all-lowercase, I'm curious as to your thoughts on a related question. What of an individual who prefers their name be written with lowercase letters? To use my own handle as an example, imagine that I requested that others refer to me as "ava" rather than "Ava", and had styled my display name accordingly. Does your opinion vary depending on whether it's a chosen name as opposed to a handle?

I have someone in my circles who prefers her name be written thusly, and while I occasionally find her somewhat inappropriately (unfairly? rashly? my vocabulary fails me at present...) militant about the topic when strangers err, I have no opposition to using the name for her as she requests, whereas I comparatively share your reservations about the use of capitalized pronouns and their associations with dynamics of power/relationship between parties.

I wonder too how I might feel should a requested name require other deviations from standard grammar, such as unusual punctuation. Were I to identify myself as "Ava!" it would certainly cause some occasionally grammatical frustrations, but I wonder if a reason given might affect the perception either in favor or against adoption. For example, the Sharks! installation rather literally evokes exclamation through its name.
