`filestatus` Subcommand cannot handle mismatch between file extension and encrypted file format.

[Jafner]

I have a file secrets.env where the plain content is dotenv formatted.
I encrypt all files to json format.

When I run sops filestatus secrets.env I get:

[CMD]    FATA[0000] cannot check file status: cannot load encrypted file: invalid dotenv input line: {

I can decrypt the file just fine with sops decrypt --input-type json secrets.env

Is there another programmatic way to determine whether a file is properly sops-encrypted?
