Hi Amanda,

This is mostly Ok to register. Some questions/comments below:

This looks like 2 different formats, but if they are similar enough, 
reuse of the same media type is Ok.

I question the statement about integrity, considering the statement 
above about executable scripts. But Ok.

This section is about backward compatibility with earlier version of the 
format. So I think the above text doesn't quite fit that and thus is not 
needed.

(The template already has a similar text in the "Restrictions on usage", 
which is fine.)

The binary format is entirely binary. The text-based format is usually
8-bit text, but MAY have lines longer than 998 octets, which qualifies
as binary per RFC 2045 section 2.8.

Security considerations: Godot resource files may contain arbitrarily
many levels of nested content. The types of nested content include
executable GDScript code, or possibly other executable content. It is
trivial to craft a malicious file which can be loaded by Godot and
escape into the operating system. Therefore, sandboxing is required
when loading untrusted files.

Godot resource files do not require privacy or integrity services.</pre>

Godot resource files may link to other Godot files, such as Godot
scenes, Godot resources, GDScript files, GDShader files, and more.
This is done through Godot referencing syntaxes, such as project-
relative path, project-wide unique ID, or class name.

Applications which use this media: Godot Engine, an open source 2D and
3D game engine.

Fragment identifier considerations: N/A

Restrictions on usage: Godot resource files may be useful for other
software to load, but implementations attempting to load them are not
guaranteed to keep working over time. Other software may choose to
implement support for loading Godot resources, but this is not
encouraged.

Provisional registration? (standards tree only): No

Additional information:

1. Deprecated alias names for this type: application/x-godot-resource
2. Magic number(s): RSCC for *.res only
3. File extension(s): *.tres *.res
4. Macintosh file type code: N/A
5. Object Identifiers: N/A

General Comments: The primary purpose of registering Godot-specific
formats is to define them, providing documentation of their
characteristics to non-Godot software, and provide a stable vendor-
scoped MIME type going forward, that being
`application/vnd.godot.resource` in this case. However, there is no
expectation of other software adopting Godot-specific formats or
adding support for loading them.
