Maybe a better solution instead of "don't do it!" might be to change:
x[[j]] <- if(length(dim(xj)) != 2L) xj[i] else xj[i, , drop = FALSE]
x[[j]] <- if(length(dim(xj)) < 2L) xj[i] else do.call("[",c(list(xj,i), rep(list(bquote()), length(dim(xj))-1L), list(drop = FALSE)))
Would this be possible and work?

Please refer to Jeff Newmiller's response. I believe that your further
exploration of indexing a data frame containing an array column
demonstrates his point: don't do it!
As this discussion could now devolve into a morass of personal opinion
(such as the above), if you or others care to continue, please do so
**offlist**. However, I have nothing further to say in any case.
