It's an interesting situation because it's obviously meant to honour the authors but in doing so it's speaking for them. It relies on the idea that these authors were women who took pseudonyms because of the society they were in rather than fully by choice.
The description of George Sand stood out to me
> Amantine Aurore Dupin, the 19th-century author better known as George Sand, who famously scandalised society by wearing male clothing and smoking cigars in public.
Wouldn't using a masculine name and wearing masculine clothing be grounds to consider her in fact a him, a transgender man? Today, Marsha P. Johnson is considered to be a trans woman rather than a gay man yet she never used the term. Admittedly, Johnson also used feminine pronouns but so have many other gay men.
It reminds me of Foone's Don’t Deadname the Dead https://foone.wordpress.com/2019/04/27/dont-deadname-the-dea...
