delete obsolte developer keys

Dear all,

the link below describes how to delete obsolte developer keys.

https://wiki.scn.sap.com/wiki/display/Security/How+to+remove+old+keys+of+developers+DEVACCESS+table

As it is not officially supported by SAP my question to you:

Have you already used this way to get rid of the old developer keys ?

Does it work or have you had problems afterwards ?

Thanks and kind regards,

Arnd
