Common? Only once then people figure out to never again put support in the nut packers or hole os com up with an even better solution than using nuts. Like heated brass thread inserts or just model threads in the plastic.
There are many solutions for dealing with threads for screws and all of them can be as strong as the screw. If you have enough depth for about 8 screw diameters of thread engagement then printing threads in a deep blind hole works (no support) Pushing in brass thread inserts with a soldering iron works too. Nut pockets work too but as you found out they don't need support inside. I use mostly either M3 or M4 size screws. It surprised me the first time that my printer can print usable M3 threads in PLA. Cura allows you to have different printer settings in different areas of the same part. It is some work to do this But you can have support under large overhangs and none in the nut pockets A good shortcut with holes that works in metal and plastic is to always try to use through holes and not blind holes. They are easier to tap in both metal and in plastic easier to clean out as pushing out debris is easier than pulling it out. But if your design used nut pockets then the holes must go clear through, try punching out the support with a punch that is the minor thread diameter, then clean up with a tap.
