PM: The non-Halachic concerns will probably get modded. We’ll leave it at calling them political.
And I don’t know of any Poskim who still hold of issues by the wall. The issues can possibly exist depending on how you read combine certain Sugyos. The Avnei Nezer has a T’shuvah explaining what the possible issues could be and why he thinks they are no problem at all. And I have no recollection whatsoever as to where that T’shuvah is, sorry.
