C_ChangeLabel/C_ClearToken

Hi, Is there interest in adding (at least) 2 more functions to the PKCS#11 specification:
a) C_ChangeLabel - to change the token label, without emptying its contents (i.e., not C_InitToken)
b) C_ClearToken - to explicitly empty all the objects currently on a token but leave it otherwise intact (i.e., again, not C_InitToken) If there is interest, then we can pursue the idea, make it pretty, and so on.
Thanks, D.
