Is it necessary to add shims for the stabilizers? I read somewhere that for Owlab stabs it is not necessary, but on the Drop website it says that the stabilizers are Drop's phantom stabilizers. My keyboard tech is "scaring" me to have shims added to my stabs as he said without the shims the stabilizers might damage the board/cut the circuit. I told him if shims are necessary then Drop would have added it on under the stabs already. Else, there will be reviews giving the warning that shims are necessary to be added. Of course I was not "fooled" and started searching if what he was saying was true or simple marketing so I would have the board modded, which I do not want anyway as I like it out of the box (except for changing the switches and keycaps).
