I don't think anybody here is a boxing historian.
Kirk is.
Here's one of the things about western combat sports (and combat sports in general, this can apply equally to kendo) is that they tend to test a very limited skillset. Foil fencing is much simpler than longsword or messer fencing, and modern boxing has a very restrictive ruleset compared to pre-MQB rules. Somewhere along the line competition became more important than a more serious application of MA. It was considered more important that someone could score a "touch" with a foil than skewer someone with a smallsword while disarming him or taking him down with a trip. It also became more important that someone get a pin in wrestling than break the opponent's arm. It became more important that boxing matches be settled with big gloves and only punches than bare knuckles and takedowns.
Perhaps the sportification of an art necessitates a reduction in the amount of techniques? Even in tournament HEMA, there are banned technques, and rightfully so. We want people to survive tourneys.
