When uploading a certificate via Kleopatra you always get the same warning text, regardless if its your own or another ones. And the keyserver setting is not taken into account either. If its a public keyserver or a local AD does make a difference, though.
Current text:
<para>When OpenPGP certificates have been exported to a public directory server, it is nearly impossible to remove them again.</para><para>Before exporting your certificate to a public directory server, make sure that you have created a revocation certificate so you can revoke the certificate if needed later.</para><para>Are you sure you want to continue?</para>
The warning about the revocation certificate probably obsolete for your own certificates, too, as it is automatically created on key generation nowadays.
Regarding text changes because of public keyserver via AD, there also is ticket T6663 in the context of certification.
