Patch ordering:
Patch 1 already adds the new package to PROVIDES while building the
package comes later with patch 2. That looks inconsistent.

I would vote for merging patch 1 and 2.

How long does it take to build that additional package? That additional
(and maybe unneeded) packet is being build unconditionally, right? As
kernel builds are normally compute intense that might matter for some
users.

Should we better hide that new "feature" / packet behind a feature flag
/ recipe variable?

Best regards,
Florian
