Is the Jr Welter Division necessary?

In 1922 Mike Collins, the publisher of a Minneapolis weekly newspaper, the Boxing Blade, created the light welterweight category and asked his readers to vote for the man they felt was the best fighter at 140 pounds. Mitchell won the balloting and was recognized on November 15, 1922, as the first light welterweight champion. The NBA followed suit and recognized Mitchell as champion.
Mitchell defended his title at least six times. One of those defenses, a 1925 fight against James "Red" Herring" , was mired in controversy. Herring won by disqualification and claimed the light welterweight championship. The Wisconsin Commission and the NBA both declined to recognize Herring as champion, however.
His defense agains Mushy Callahan saw Mitchell lose his title in September 1926. After losing to Callahan, Mitchell never won another fight and retired in 1928.

Barney Ross won a 10-round decision (a fight whose outcome is determined by judges’ scoring) over American Tony Canzoneri on June 23, 1933, to gain simultaneously the world lightweight and junior welterweight (also known as super lightweight) titles. On Sept. 18, 1933, Ross won a 15-round decision in a rematch with Canzoneri for both titles. Following three more successful defenses of his junior welterweight title,

There was not widespread acceptance of this new weight division in its early years, and the New York State Athletic Commission withdrew recognition of it in 1930. The National Boxing Association continued to recognize it until its champion Barney Ross relinquished the title in 1935 to concentrate on regaining the welterweight championship.
A few commissions recognized bouts in the 1940s as being for the light welterweight title, but the modern beginnings of this championship date from 1959 when Carlos Ortiz won the vacant title with a victory over Kenny Lane . Both the WBA and WBC recognized the same champions until 1967, when the WBC stripped Paul Fuji of the title and matched Pedro Adique and Adolph Pruitt for their version of the championship. Adigue won a fifteen round decision. The IBF recognized Aaron Pryor as its first champion in 1984.
Julio Cesar Chavez holds the division record for the most consecutive title defenses with 12. He also defended the title an additional 4 times after regaining it.[4]

 

Maybe not necessary but I don't think it's a bad thing.

 

None of the "jr" or "super" weight classes are necessary, tbh. We'd have a better sport without them.

 

. . . if you only have one division then you don't have any divisions.
