I personally don't like being locked-in: I like to have the choice to call the file whatever I want and put it wherever I want inside the package.

Might be annoying to type on non-english keyboard (and to remember another english word?… I guess it would be like you and I having to learn some strange Chinese word). It's probably not a huge pain, but if we can make someone's life a little easier, I think it's a good thing.

There is that too, yes.

Right. I've put in the spec: "It is OPTIONAL for a user agent to support the media types listed in the default splash-screen table."

Authoring Guideline: At the time of writing, there is limited support on devices for displaying SVG as a splash screen. As such, if you do include an SVG-based splash screen file, it is strongly recommended that you also include a splash screen file in one of more of the other formats listed in the default splash-screen table.
