I tend to agree with you , I gave up breeding honey consuming drones for Varroa to infest when the frames could have raised worker bees instead If I'd used standard brood wax instead of drone wax. Plus the queen only has so many eggs in her life , so why waste them on excess drone brood that occupied workers efforts who could have been better employed elsewhere in the hive ?
Purposely encouraging additional drone brood production must have some effect on the strength of the hive & it's capabilities . It is often argued by some that the varroa reduction gained by freezing sealed infected drone brood is somehow worth it. i considered the loss of two brood comb faces in the brood box as not worthwhile even if I double brooded the hives.
It also saved me from thinking of buying my own wax mould for making drone wax ( I already had the standard mould & queen cup forms )
