It did take manufacturers several decades to get to this point, and neither low-end kit, nor reassuringly expensive boxes were necessarily quick to join this trend. Not necessarily feasible to have everything secured too, when a rack's keyboard would be moved between servers at the top/middle//bottom of the cab. Especially in places which didn't have the budget for expensive serial console servers (only for a moderately expensive proprietary keyboard).
