I asked the support to proceed. gandi.net reply No, this status prevent the domain name to be deleted, even in the case it’s not renewed. This status in only used for some legal issue, to prevent ‘proof’ to be deleted. (For whonix.org .) I’ll ask gandi.net about this again in case namecheap.com proceeds with setting the clientDeleteProhibited flag.
