Shaving of cylinder head requires more expertise, precision and machinery.
Making groove too requires expertise and precision. However not much of sophisticated machinery required.
You're spot on when you say grooving decreases CR. Yes. But the advantages of better combustion surpasses the unnoticable decrease in CR by making the groove. So, guys, deeper the groove, CR will go more bad. Need to find an optimal depth and length, and most important position of the groove.
Booster gauge, IMO too, grooving, coupled with a precise head shave might give a better result.
I am really looking forward to these modifications. I believe this job is not a DIY for most of us. Only those who have keen interest, understanding and access to the necessary resources go ahead with this job, as a DIY.
