As historical reference, please see the discussion in LuCI PR #855 in 2016, 
when that aspect was discussed:

It can be cumbersome to make a user-space package depend on alternative 
kernel package variants depending on the kernel version, as  we have some 
package targets where the user-space package build SDK kernel version might 
differ from the target SDK kernel. There were major difficulties with SQM & 
cake a year ago.

See https://github.com/openwrt/packages/issues/12072

There the solution was an additional virtual kernel package, which could then 
handle the kernel mainline / oot dependency difference inside the target.
