Please consider naming guideline [ADFng1-02008] in the "ADF Naming and Project Layout Guidelines v1.00" .
[ADFng1-02008] - Application level deployment profile names - For deployment profiles created at the application workspace level, the deployment profile name should be the same as the application workspace name.
Trying to avoid using the same name for different things, is a general guidline that can help to avoid confusion.
In case of naming guideline [ADFng1-02008], confusion about when a name refers to a deployment profile or an application workspace name can be avoided by adding a suffix "-dp" to the deployment profile name.
Such confusion could occur when referring to a deployment profile while using ojdeploy, or when referring to a deployment profile in general.
Also when multiple deployment profiles exist, a "-dp" suffix would allow to easily recognise a name as a deployment profile name.
Given that different naming guidelines  suggest to "have the suffix", this also does not seem to conflict with naming guideline [ADFng1-01014], "Don't use Hungarian notation".
