Two things:

1) The behavior is clearly a bug. The reason files are made read-only is=20
to prevent their being written (at least to prevent them from being=20
written casually). At least when Vim does this, it requires the user to=20
use the "!" modifier to the writing command.

2) I'm curious about how much extra risk of data loss is actually posed=20
by disabling two-stage save? What vulnerabilities exist? What must go=20
wrong for data to be lost? Will the user get a positive indication when=20
it happens? If an error occurs during a save initiated as a result of=20
exiting the application with unsaved changes, will the program exit be=20
cancelled and the user given a chance to save again or elsewhere?
