Chair admit that to do this you need sequence breaks. Now sequence breaks are fine but why did they purposely put it in the game. Sure something like Super Metroid has sequence breaks but not purposely. I love this game but I feel like with this they were trying to hard to be like Metroid and Castlevania.

I kind of applaud it. Glitching is something some people do for fun, and often takes a lot of skill and patience (I did so myself in THPS4). I think they know that some people will push the boundaries of the game, and those people are usually their most loyal fans. It's nice to see a reward for them.

Well, is sequence breaking put intentionally into the game still sequence breaking? Personally it is, but  it's just semantics really.
 
And besides, everyone who does know how to do the sequence breaking to make this possible have their lips shut, so it's basically discovering new techniques the old-fashioned way anyway.
