A previous repair guy put a button right in the nook of the neck at the 12th, whose removal left a decorative hole, which you can now see at the lower right. This made the guitar extremely stable with the strap. However, it also created the situation where both the button and the strap interfered with the motion of the hand. I just had another luthier/repair guy reposition it so it wouldn't get in the way of the thumb. I showed him Krylov's photos

To place it where krylov suggested would require the button to be rotated to the east/right face of the saddle. The current placement shown above allows the guitar to fall forward a little. I'm thinking the button at least could be repositioned again to the very edge where it meets the flat part of the neck/saddle, or even high up on flat part of the neck saddle. Whatsha think? The number of holes in the guitar doesn't matter any more because there are already too many for my terrier to count. Besides, holes drilled for legitimate purposes only increases a guitar's value. Of course, one of these legitimate purposes is to increase the value of my guitar.
P.S.
Luthiers/Repair guys really don't know where to place buttons for stability and lack of interference with the left hand. I now have had a total of three button placements, all in ridiculous positions placed by the manufacturer (worst position possible on the backside of the guitar) and luthiers. You will have to show them the exact placement.
For situations where the guitar is unstable or falls forward because the left button is misplaced, placing the strap over the rightward bout can fix the situation and create a very stable position. For example this is the fix for the misplaced button shown in the previous photo. The photo below gives the idea but the strap will really end up right on the edge with no bout visible to the right of the strap.
